But GPS receivers in general are effected by multipath and atmospheric effects and hence their performance may be decreased, especially in challenging environments that directly affects the usage of satellite-based positioning in traffic-relevant and by that safety-critical systems. Therefore, this paper describes, based on an exemplary implementation of an Advanced Software-Defined radio receiver (ASDR) for Global Navigation Satellite Systems, the impact of the direct receiver surrounding. In addition, a so-called Smart Constellation Selection (SCS) as pre-positioning routine will be introduced to increase the accuracy by just using already available data at the receiver side. Next to the implementation of the ASDR itself, the functionality and performance of the SCS will be explained. In addition, this contribution contains the introduction of a freely available database with geo-referenced GPS measurements including web-based analysis functionalities to enable other researches to test and evaluate their ideas for future GNSS enhancements.","PeriodicalId":219477,"journal":{"name":"2013 IEEE 20th Symposium on Communications and Vehicular Technology in the Benelux (SCVT)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122598718","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, several sensing applications running on a smartphone can degrade the device performance. This can be overcome by using lightweight application protocols which improve the smartphone performance in terms of bandwidth consumption, battery lifetime and communication latency. This work focuses on two emerging application protocols: the Message Queuing Telemetry Transport (MQTT) and the Constrained Application Protocol (CoAP). Although both protocols have been designed for highly constrained environments such as sensors, they are also appropriate to be adopted in smartphone applications. We provide a qualitative and quantitative comparison between MQTT and CoAP when used as smartphone application protocols and we give preliminary indications on the application scenarios in which either protocol should be adopted. While MQTT has already been adopted in smartphone applications, CoAP is relatively new and has up to now mainly been considered for sensors and actuators. Our comparison shows that CoAP can be a valid alternative to MQTT for certain application scenarios.","PeriodicalId":219477,"journal":{"name":"2013 IEEE 20th Symposium on Communications and Vehicular Technology in the Benelux (SCVT)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130898118","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}

Currently most 4th generation wireless communication systems employ the Orthogonal Frequency Division Multiple Access (OFDMA) technology in the downlink (DL) part of their physical layer. In this paper we present a simulation-based performance analysis of the Priority-Aware Extended eOCSA (PA-EeOCSA) DL frame packing algorithm under mixed VoIP and uncorrelated data traffic. For VoIP traffic, the ON-SID model has been used and the packing efficiency of both the eOCSA and PA-EeOCSA algorithms have been compared. Simulation results point out that in terms of mean percentage of unallocated bursts and the number of slots allocated on average, the PA-EeOCSA algorithm performs more efficiently in comparison to eOCSA. Results also show that with data users fixed at 20, between 40-45 VoIP users can be admitted if the mean percentage of unallocated bursts is to be maintained below 3.0 %. Recall that, a low mean percentage of unallocated bursts is imperative in order to keep the overall packet loss rate below a tolerable limit.","PeriodicalId":219477,"journal":{"name":"2013 IEEE 20th Symposium on Communications and Vehicular Technology in the Benelux (SCVT)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121568506","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 demand for high rate wireless indoor coverage while providing complete support to the existing wireless technologies is a big challenge. The future proof centralized optical fiber indoor back haul for efficient indoor coverage is gaining a lot of attention recently. Physical layer techniques like multiuser MIMO (MU-MIMO) is becoming an inevitable approach in this regard. Quality of service serves as the most attractive feature that should be ensured among the mobile terminals (MTs). In this work we try to study the effects of imperfections in channel knowledge owing to estimation errors. We study the effects of it on our previously proposed throughput fair successive signal to leakage and noise ratio (SLNR) precoding algorithm [1] for such a fiber-wireless (Fi-Wi) MU-MIMO indoor. Our algorithm has been shown previously to achieve maximal fairness. In this paper we use MMSE alterations to significantly reduce the effect of estimation errors for our scheme. We provide a lower bound on the sum rate achievable with imperfect CSIT. In this paper we also compare different power allocation policies. Power allocation policies plays an important part in improving the performance of the system in terms of BER of the worst case user. We show that channel adaptive power allocation guarantees approximately 3dB SNR improvement over the equal power allocation policy for BER of 10-7.","PeriodicalId":219477,"journal":{"name":"2013 IEEE 20th Symposium on Communications and Vehicular Technology in the Benelux (SCVT)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128567150","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}
