The AMAS method which efficiently updates and distributes the road information collected by mobility and roadside sensors to a dynamic map (DM) enables automatic mobility control with high reliability and accuracy. In order to verify the renewal and dispersion of DM, we have developed a wireless electronic traffic mirror (WETM) that acquires road information, recognizes road objects and transfers recognition information with a wireless communication system. Additionally, to meet the safety requirements, the AMAS must provide the wireless connection best suited for mobility. In order to provide optimum wireless connectivity, real-time wireless channel monitoring, which measures the quality of wireless channels with interference, is an important task in the AMAS. In this paper, the real-time wireless channel monitoring system in cooperation with the developed WETM is introduced, and in order to clarify the reason why the quality of the road was changed, clear evidence of the visibility of the road situation is clarified.","PeriodicalId":298927,"journal":{"name":"2019 22nd International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125596818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"How to combine the Technology Multi Business Innovation concept with the CDIO framework - The MBMI Case Challenge Process Model","authors":"Jane Flarup, G. Andersen, P. Lindgren","doi":"10.1109/WPMC48795.2019.9096190","DOIUrl":"https://doi.org/10.1109/WPMC48795.2019.9096190","url":null,"abstract":"Many Universities and businesses have focus on change in the educational didactics approach to the engineering studies. This focus and change are supported by industries, as there is an increasing strong demand to change engineering student’s mindset to be able to also bridge technology to business models and business. The focus on supporting educational activities, linking engineering students mindset to a technological business model innovation mindset for the purpose to apply their engineering academic, theoretical knowledge to business modelling and business - and in this case the Multi Business Model Innovation (MBMI) approach – is simply based in the fact that technology innovation needs business models and vice versa. Technology need to complement and become embedded in business models. To facilitate this change and related activities, AU has over some years developed two new concepts - The AU Case Competition Network challenge [1] and The TBMI Challenge [2]. The paper reports on experiment at ‘CDIO Academy’ conference held at Aarhus University and in June/July 2019 where CGC research group carried out a 7-week TBMI Summer School TBMI Challenge. The challenge referred to in this paper focus mainly on the AU Case Competition Challenge based on The CDIO™ INITIATIVE [2]. The paper reflects on the results of an experiment with the aim to form a pedagogical and business model innovation frame for Case and TBMI challenge. The paper presents a framework model to facilitate engineering student teams’ and in extension interdisciplinary engineering teams in businesses. The paper reports on the working and learning progression in case challenge engineering workspaces, and try to answer the research question: “How to clarify the transition of shifts in the work process from start to the end of a case or TBMI challenge? The paper offers a preliminary model, which can be added to the MBMI-concept model [3], [4] focusing on facilitating engineering student and cross interdisciplinary engineering teams in businesses in engineering workspaces by clarifying work processes, progression and transition shifts.","PeriodicalId":298927,"journal":{"name":"2019 22nd International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125606666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The design circuit will contain a resistive temperature sensor connected in a bridge configuration and a capacitive humidity sensor. For the data to be read by the microcontroller, a signal conditioning block will be designed to amplify the outputs of the two sensors and bring them into the input range of the analog-to-digital converter. USB heating elements will be used to adjust the temperature. An 8-bit ATMEL family microcontroller will be used and the program will be developed using the Code Vision AVR compiler. In order to validate the data, a comparison will be made between the monitoring system described above and a LIBELIUM Smart Environment plate containing calibrated sensors that provide very good temperature and humidity values based on a set sampling frequency. The development environment for the LIBELIUM is ARDUINO, which will send the data over the Wi-Fi network using the MQTT protocol to a SQL database with a Grafana web interface for viewing. In order to alert medical staff to exceeding the range of temperature or humidity values, I will also implement a code to send email alerts from the Grafana web interface that communicates with LIBELIUM Smart Environment.","PeriodicalId":298927,"journal":{"name":"2019 22nd International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121594839","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In general, the NOMA signal detection becomes complicated as the number of users increases. Although the SCMA is a kind of low-density spreading, it requires an interference canceller. In this paper, Gaussian belief propagation (GaBP) is applied to detecting the SCMA signals because the complexity order of GaBP is the square of the graph size. In addition, we apply CRCaided stopping of iterative processes to GaBP. The simulation results show that the CRC-aided GaBP provides much lower FER performance and that the number of iterations is highly reduced.","PeriodicalId":298927,"journal":{"name":"2019 22nd International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"46 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113984318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional methods such as the rotating element electric field vector (REV) method for the elements of array antennas do not account for the mutual coupling between elements. When an antenna calibration is not performed adequately, the radiation intensity of the radio waves in the undesired direction increases, causing interference with other satellites which are not intended. In order to overcome this drawback, a model of an array antenna including a coupling between antenna elements is constructed. Using this model, the estimation problem of the effect of the mutual coupling is formulated as formulation problem. Finally, a calibration method based on the solution of the optimization problem is derived.","PeriodicalId":298927,"journal":{"name":"2019 22nd International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123009791","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The solution is developed and evaluated in two stages, simulation and experimental. We simulated the DVB-T transmitter, channel, and receiver to analyze bit error rate (BER) and video quality for different channel conditions (BER) and different modulation techniques i.e. QPSK, 16-QAM, and 64-QAM. Experimentally, DVB-T transmitter and receiver are implemented using software defined radio (SDR) and a commercial DVB-T receiver. We have proposed the system architecture for adaptive broadcast system using DVB- T standard for broadcasting multimedia content and Wi-Fi for feedback link from all receivers to base station. A modulation parameter selection algorithm is also proposed in this work which can be used to serve all the users which are connected to the base station. This algorithm suggest that BS first receives feedback data from all the receivers and finds out the most robust modulation parameter so that all the users can receive the broadcast content. Finally, we highlight the advantage of adaptive modulation technique over fix modulation technique. Video quality matrix is compared for transmitted video and received video for different modulation techniques by varying the distance between transmitter and receiver to compare the performance of adaptive and non-adaptive broadcasting system and useful data rate vs. SNR graph is plotted and discussed for adaptive modulation system and fix modulation system.","PeriodicalId":298927,"journal":{"name":"2019 22nd International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"466 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123280199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many communication systems commonly used for terrestrial users have been applied to maritime environments. The objective of this paper is to analyze the path loss characteristics of long term evolution (LTE) system and confirm its feasibility in maritime environments. In this purpose, we developed the test-bed for LTE-Maritime at coastline in the Republic of Korea and conducted onboard experiments for reference signal received power (RSRP) and throughput measurements. The measured RSRP values are compared with three conventional path loss models of free space path loss (FSPL), two ray (TR) path loss, Okumura-Hata (OH) model. The comparison results show that the existing models tend to underestimate the RSRP degradation suffered from maritime environment and there is a notable difference between the experiment data and path loss models. In order to analyze their accuracy, root mean square error (RMSE) for each model is calculated according to the distance between a transmitter and a receiver, and the results show that the expected error becomes high with increasing distance. In addition, the throughput measurements show that LTE can provide high-speed data services in the order of Mbps with the long communication distance up to 100 km.","PeriodicalId":298927,"journal":{"name":"2019 22nd International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128686822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, relay selection to result in the strongest link becomes the critical technology to facilitate RAN using mmWave. A disruptive approach toward relay selection is to take advantage of existing operating data and apply appropriate artificial neural networks (ANN) and deep learning algorithms to alleviate severe fading in mmWave band. In this paper, we apply classification techniques using ANN with multilayer perception to predict the path loss of multiple transmitted links and base on a certain loss level, and thus execute effective relay selection, which also recommends the handover to an appropriate path. ANN with multilayer perception are compared with other ML algorithms to demonstrate effectiveness for relay selection in 5G-NR.","PeriodicalId":298927,"journal":{"name":"2019 22nd International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128719223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
