The strategy is based on mapping the received signals into sub-groups. The mapping process aims to achieve the highest rates for each of the sub-groups. After this mapping process, the conventional successive interference cancellation strategy is applied to each of the sub-groups for the signal separation process. According to analytical, asymptotic and Monte-Carlo simulation results, the advanced successive cancellation strategy outperforms the conventional successive interference cancellation strategy in terms of the outage performance. In addition, the new strategy also provides a new perspective for the user delay decoding process.","PeriodicalId":229131,"journal":{"name":"2018 26th Telecommunications Forum (TELFOR)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115226983","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}

Recognizing images, sounds, classification - these problems require serious processor power and memory for neural network learning and operation. Modern mobile devices have quite good characteristics for executing only the primary layers of deep neural networks, but there are not enough resources for entire networks. Since the training of non-mobile networks for mobile devices takes place separately on external resources, a method was developed for the distributed operation of a neural network with vertical partitioning sets of layers with synchronization of learning data. In some cases, the proposed approach allows to use full-sized deep neural networks on mobile device, where they are needed without overloading the communication channel and device resources.","PeriodicalId":229131,"journal":{"name":"2018 26th Telecommunications Forum (TELFOR)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127271299","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 signal is reconstructed using an iterative hard thresholding algorithm, modified for the complex-valued binary measurements. The considered CS approach is particularly suitable for hardware realizations. The reconstruction performance is validated numerically, and compared with the traditional CS reconstruction based on quantized digital measurements.","PeriodicalId":229131,"journal":{"name":"2018 26th Telecommunications Forum (TELFOR)","volume":"32 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116423347","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}
