By maximizing the mutual information, we first investigate the designs of APSK modulations suitable for communication over nonlinear wireless channels. Then we propose a unified FPGA-based hardware-efficient architecture which combines the capacity-approaching LDPC decoders with four APSK modulation formats, including Gray-mapping-based 8-APSK, 16-APSK, 32-APSK, and 64-APSK. The proposed architecture allows the flexibility of the FEC-encoded signal to be received by legacy test-range systems. The emulation results show that such an LDPC-coded modulation scheme can adapt to wide range of received signal-to-noise ratios, ranging from 9.4 dB to 21.4 dB, by using different LDPC codes and/or modulation formats.","PeriodicalId":206778,"journal":{"name":"2017 13th International Conference on Advanced Technologies, Systems and Services in Telecommunications (TELSIKS)","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121394150","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 infinite series expression for second order statistical measure such as average level crossing rate (LCR) is obtained, numerically presented and discussed regarding different system model parameters. Precisely, the effects of Gamma long term fading severity parameter of desired signal, Gamma long term fading severity parameter of co-channel interference (CCI), shadowing correlation parameter, average signal power of desired signal as well as average power of CCI on LCR are thoroughly examined.","PeriodicalId":206778,"journal":{"name":"2017 13th International Conference on Advanced Technologies, Systems and Services in Telecommunications (TELSIKS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129632189","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}

Tesla's invention was the first wireless control device with its own command logic. Historically, this device was the first completely realized remote control robot. Modelling was done in cooperation with the Nikola Tesla Museum of Belgrade whose original documents and model were exploited for virtual model making. Stereoscopic modelling was achieved by precisely observing original blueprints and the physical prototype owned by the Museum. Following this, the animation process and its realisation in a VR environment was achieved in consultation with a number of experts. The project deliverables now feature in the standard exhibition of the Museum.","PeriodicalId":206778,"journal":{"name":"2017 13th International Conference on Advanced Technologies, Systems and Services in Telecommunications (TELSIKS)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116759790","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 architectures enables a trade off between the throughput, computational and hardware resources. As a special case, we derive previously proposed flooding schedule URAPP decoder and propose new type of the URAPP decoder which uses shuffled scheduling. We conduct a rigorous complexity analysis and provide new formulas for the URAPP decoder throughput in terms of hardware resources and memory requirements. The analysis confirms that the shuffled decoder represents an optimal solution if the hardware resources are limited, which makes it attractive in practical applications. The results are verified by simulations for the case of finite geometry LDPC codes.","PeriodicalId":206778,"journal":{"name":"2017 13th International Conference on Advanced Technologies, Systems and Services in Telecommunications (TELSIKS)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125529355","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}
