Terahertz frequency bands, especially around 300 GHz, has been considered for future wireless communications. As far as we know, no work has considered the rain induced interference at THz frequencies. In this work, we evaluate the rain induced interference at 300 GHz. Results are calculated also at 60 GHz in order to make a comparison. We combined bistatic radar equation, first order multiple scattering approximation and full Mie scattering calculations to existing drop size distribution models to estimate interference due to rain. Considered effective path lengths between transmitter and receiver are 100 m and 500 m and the effect of selected drop size distribution is studied. Overall interference levels was observed to be approximately 20 dBm smaller at 300 GHz than at 60 GHz and angular dependency of interfering power was much more forward oriented for 300 GHz frequency. The results show that rain induces interference has significantly different behaviour at THz as compared to lower frequencies.","PeriodicalId":426086,"journal":{"name":"2019 IEEE International Conference on Communications Workshops (ICC Workshops)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123859284","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 is demonstrated that the multi-directional receiver (MDR), as a simple yet effective and practical receiver structure, significantly improves the performance compared to a conventional benchmark receiver design, called screen receiver (SR). In MDR, multiple photodetectors (PDs) are placed on different sides of a handheld device, e.g., a smartphone. The channel condition number, defined as the ratio of maximum to minimum eigenvalues of the channel matrix, is statistically studied for MDR and SR. It is observed that the highly reduced values of channel condition numbers for MDR result in more than 16 dB reduction of required signal-to-noise ratio (SNR) for SMX and SM at a target bit error ratio (BER). It is shown that, particularly for a high target spectral efficiency, incorporating MDR in conjunction with an appropriate MIMO technique can be a effective solution for future LiFi applications.","PeriodicalId":426086,"journal":{"name":"2019 IEEE International Conference on Communications Workshops (ICC Workshops)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133896501","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 moving D2D-enabled heterogeneous ultra-dense networks (H-UDNs), it will cause heavy system overhead from the frequent mode selection between D2D mode and cellular mode, which is also belong to handover strategies. Thus, the optimization of mode selection strategy is needed urgently. In this paper, for the mode selection occurring from cellular communication mode to D2D communication mode (C2D), we propose a feed-forward neural network (FFNN) based multi-attribute D2D transmitter choosing strategy. The proposed strategy implements FFNN model, meanwhile combine the stochastic geometry based long-term analytical results with instant parameters involved in mode selection process. As a result, our proposed strategy brings improvements to the mode selection performance, which can be observed in reducing the mode selection probability and increasing the D2D mode dwell time. Moreover, the system overhead is further reduced on the basis of achieving full-spectrum reuse.","PeriodicalId":426086,"journal":{"name":"2019 IEEE International Conference on Communications Workshops (ICC Workshops)","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132749669","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}
