Sámano-Robles","doi":"10.1109/RTUWO.2016.7821881","DOIUrl":"https://doi.org/10.1109/RTUWO.2016.7821881","url":null,"abstract":"Network diversity multiple access (NDMA) is the family of algorithms with the highest potential throughput in the literature of signal-processing assisted random access protocols. NDMA uses the concept of protocol-induced retransmissions to create an adaptive source of diversity. This diversity is used to resolve packet collisions employing signal separation tools without the explicit need (or as a complement) of a multiple antenna receiver. This paper proposes a further improvement on the performance of NDMA by allowing each terminal access to an outdated copy of its individual channel state information (CSI). Based on this decentralized CSI, each terminal conveniently decides to transmit only if the estimated channel gain surpasses a threshold that is optimized to maximize performance. This ensures that the probability of terminal presence detection, and thus the probability of correct estimation of the collision multiplicity are considerably improved at the receiver end. The paper is focused on the modelling of the receiver operational characteristic (ROC) of the terminal presence detector considering that the CSI used by each terminal is potentially inaccurate (outdated) due to feedback delay. The results indicate that when the correlation coefficient that describes the accuracy of the available CSI tends to zero (ρ → 0), the scheme degrades into the conventional NDMA. By contrast, when the quality of the channel state information improves (ρ → 1), the throughput can nearly achieve the nominal channel rate (minimum throughput penalty). The selection of the detector thresholds for channel gain and terminal presence is optimized to maximize system performance.","PeriodicalId":229246,"journal":{"name":"2016 Advances in Wireless and Optical Communications (RTUWO)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114476833","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}

It makes the bidirectional transfer of time-critical control, diagnostics, and calibration (CoDiCa) data wireless and hence increases the HIL test setup flexibility as well as opens up novel opportunities for testing automotive ECUs or autonomous driving systems. The introduced approach applies the robust physical layer IEEE 802.11p and exploits multiple parallel radio front ends. This configuration enables a multi-channel operation and enhances the deterministic dynamic spectrum access in the coexistence-afflicted 2.4GHz industrial, scientific, and medical (ISM) frequency band required for real-time wireless CoDiCa data transmission. In addition, an adaptive spectrum access procedure is introduced that provides compliance with the revised European spectrum regulations in terms of the mandatory listen-before-talk mechanism. By employing interference measurements and link-level simulations the real-time performance of the RT-WCGW is characterized and evaluated under realistic coexistence conditions. The results show that the real-time capability of the RT-WCGW can be significantly improved by utilizing the multi-channel approach making it practicable for novel HIL test applications.","PeriodicalId":229246,"journal":{"name":"2016 Advances in Wireless and Optical Communications (RTUWO)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114211230","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}
