In order to suppress this transient noise and improve the reliability of communication, a transient noise suppressing method for radio signals based on matching pursuit algorithm is proposed. Firstly, An over-complete atomic library that matches only the transient noise in the mixed radio signal is constructed to implement the sparse decomposition of the transient noise. Then, the optimal matching atomic search of the transient noise is proceeded in the atomic library. In this paper, the GMSK modulation signal in GSM-R system is used as the radio signal to be denoised from the transient noise. The simulation results show that this method can effectively deal with the transient noise denoising problem of the radio signal with a high accuracy result and a low distortion of the radio waveform which keeps the original characteristics of the radio signal, the bit error rate of the radio signal polluted by transient noise is significantly reduced after the processing of the algorithm proposed.","PeriodicalId":339606,"journal":{"name":"2017 15th International Conference on ITS Telecommunications (ITST)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124164179","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}

While there is general agreement that an advanced human-autonomous vehicle (HAV) interaction is key to achieve the benefits of self-driving cars, it is less clear what role artificial intelligence (AI) should play in this context. While the scientific community is debating on the role and intersections of AI, autonomous vehicles and related issues, above all ethics, the automotive industry is already presenting AI-based products and services that may influence, in a direction or in another, our technological and societal futures. This paper focuses on virtual assistants, the personification of the car intelligence incorporating, among others, an algorithmic “brain”, a synthetic human “voice” and powerful sensor-based “senses”. Should virtual assistants just assist humans or replace them whenever necessary? Should their scope of action be limited to safety-related driving tasks or to any activity performed in the car or controlled from the car? Although at a very early stage of commercial development, the paper will review the state-of-the-art of in-car virtual assistants underlining their role and functions in the connected and automated driving ecosystem. By drawing from earlier reflections on automation, robots and intelligent agents, it will then identify a series of issues to be addressed by the scientific community, policy-makers and the automotive industry stakeholders.","PeriodicalId":339606,"journal":{"name":"2017 15th International Conference on ITS Telecommunications (ITST)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129602411","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 this regard European Telecommunications Standards Institute (ETSI) has standardized the Cooperative Awareness Basic Service where status messages named Cooperative Awareness Messages (CAMs) are constructed, managed and processed. With the regular exchange of CAM messages, vehicles and roadside units are constantly informed about each others position, dynamics and attributes. Due to this massive dissemination of messages, without properly congestion control, the functionality of both safety and traffic-management C-ITS applications can be compromised. In this paper we consider the ETSI Decentralized Congestion Control (DCC) mechanism and propose a new approach to cope with relative oscillation and unfairness problems. In the proposed solution vehicles adapt their behaviour and DCC decisions according to the surrounding road traffic conditions. DCC functionality and the presented solution have been then validated through an experimental, ITS G5-compliant testbed consisting of real world devices. The obtained results show an improvement in DCC performances, evaluated in terms of machine status and Channel Busy Ratio (CBR) oscillations.","PeriodicalId":339606,"journal":{"name":"2017 15th International Conference on ITS Telecommunications (ITST)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134055638","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 proposed model focuses on the communication elements, delving into the cooperative aspect between the network components. The first level of the proposed scheme is composed of a multi-sensor data fusion framework using the measurements obtained from the vehicle on-board sensors, in order to detect obstacles in front of the vehicle. The obstacle detection is based on a liner regression fusion rule, which combines the obtained features from several sensors. Once the decision is taken, the vehicle responds consequently using implicit coordination and bringing the network to an uncertain status. Hence, the second level consists on achieving a stable network by applying explicit coordination between the vehicles and the deployed infrastructures. The third level controls the entire network from a centralized perspective using long-range communication links. Using the knowledge obtained from the centralized network, optimization can be achieved using a coordination scheme based on communication. To finalize, the theoretical framework is simulated under realistic conditions obtaining promising results, in terms of obstacle avoidance and network coordination.","PeriodicalId":339606,"journal":{"name":"2017 15th International Conference on ITS Telecommunications (ITST)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134405680","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}
