We address the matching-based communication system optimization over parallel channels in wide optical spectrum. It is found that the dimension can be reduced significantly under certain line-of-sight optical wireless communication scenarios. Based on the dimension reduction, we design the quantization points in the reduced dimensional space, and store the optimal scheduling policy corresponding to each quantization point obtained in an offline manner.We first investigate the covariance of the achievable rates of the parallel channels. Then we formulate system optimization framework via matching the link gains of parallel channels to the quantization points, and obtain the sufficient conditions such that the utility loss of employing the quantization-based solution can be sufficiently small under sufficiently small quantization distortion in the reduced dimensional space. Such sufficient conditions can be satisfied for certain common optimization examples. We also address the matching-based communication system design for the matching under noisy channel estimation.","PeriodicalId":345352,"journal":{"name":"2017 IEEE Globecom Workshops (GC Wkshps)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132212430","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 the 5G era, railway communications are required to evolve from handling only the critical signaling applications, to various high data rate applications. The millimeter wave (mmWave) band is considered as a key technology, while there is a lack of deep analysis for railway propagation scenarios. In this paper, a significance analysis methodology, which analyzes and distinguishes the contributions of different railway objects to the mmWave propagation channel, is proposed. Ray tracing (RT) simulation and the ITU-R mmWave band material parameters are combined to overcome the challenges on mobile railway channel measurement, based on which close-to-real simulations can be conducted. The features of train-to-infrastructure (T2I) urban communication scenarios are studied. Statistically consistent environment models are generated automatically based on the code for design of railway infrastructure, which enables conducting extensive practical simulations and extracting parameters at ray level. The significance criteria is studied and non-trivial objects and materials are determined for T2I urban scenarios, which not only numerically indicates the influences of typical railway objects, but also provides theoretical fundamentals for efficient environment modeling for accurate RT based deterministic channel modeling.","PeriodicalId":345352,"journal":{"name":"2017 IEEE Globecom Workshops (GC Wkshps)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134145187","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 the near future, the number of battery powered devices will also significantly increase. Current security approaches are not sufficient for these issues and high-complexity cryptographic techniques are not suitable for such devices. To address these problems, physical layer (PHY) security solutions have recently emerged. Some 5G candidate techniques such as full-duplex communication (FD) and artificial noise transmission (AN) are exploited in various PHY security solutions due to their performance advantages. In this study, a scenario resembling a factory environment is considered and security level is analyzed in real-time by utilizing FD and AN methods. The aim of this analysis is to investigate physically secure transmission regions and to expand these regions by intelligently using AN. Our proposed approach is evaluated in real- time with a testbed that consists of software defined radios (SDRs). Two devices with very different front-end characteristics are utilized as eavesdroppers to analyze hardware effects on the eavesdropping performance. As observed with experiments, robust secure regions can be created by the use of AN on eavesdroppers effectively.","PeriodicalId":345352,"journal":{"name":"2017 IEEE Globecom Workshops (GC Wkshps)","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130945310","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}

A positive interference can be constructed to enhance the received signal gain by predicting the phase and magnitude of inter-user interference. Thus, we propose constructive interference optimization that maximizes the signal-to-interference and noise ratio (SINR) of users by predicting the constructive interference. Towards this end, we formulate a minimum mean square error (MMSE) problem, which is relaxed over the constructive interference region with the minimum required cumulative constrictive interference gain (CCIG) under a total power constraint. We then derive the optimal transmit signal vector as a function of Lagrange multipliers obtained by Karush-Kuhn-Tucker (KKT) conditions. Our numerical results demonstrate that the proposed data-aided precoding scheme provides more CCIG than other state-of-the-art schemes, which turns out to be useful under a mm-wave band channel with few multi-paths or non-homogeneous environment.","PeriodicalId":345352,"journal":{"name":"2017 IEEE Globecom Workshops (GC Wkshps)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133062832","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}
