This system is based on a Time-Code Division Multiple Access scheme, where the sequential emission of five BPSK modulated Kasami codes is performed to estimate the vehicle position through a multilateration procedure. The effect of the vehicle rotors on the detection of these broadband signals is experimentally analyzed for different relative powers. Preliminary results confirm the feasibility of the proposed system to provide accurate position estimates even under very low signal-to-noise ratios.","PeriodicalId":206778,"journal":{"name":"2017 13th International Conference on Advanced Technologies, Systems and Services in Telecommunications (TELSIKS)","volume":"55 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":"115966949","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 high-data rate applications running through mobile devices together with the radio access devices at the base stations (BS) cause a significant growth in energy consumption in the network accounting a large share of network operation expenditure (OpEx), as well as increased carbon emissions. Unlike an interference-free network, in the IL cellular network, a monotonically increase of the transmission power does not necessarily improve the spectral efficiency (SE) of the network. For the analysis of the EE an information theoretic approach is applied and represented as a function of the BS transmission power considering the interference signals. A gradient based optimal level solution for the BS transmission power is derived to maximize EE. A network operator can significantly reduce the energy cost by setting the transmission power of the BS at the optimum level.","PeriodicalId":206778,"journal":{"name":"2017 13th International Conference on Advanced Technologies, Systems and Services in Telecommunications (TELSIKS)","volume":"111 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":"124108620","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 all applications, the primary consideration is both transmit and receive power efficiency, but at higher power levels, other factors such as safety regulations, become relevant and require new approaches. Specific examples are given for a near-field phased array at 6.78 MHz for vehicle powering, an airborn 4.3GHz harvester and a study for a microwave large array lunar directive beaming scenario.","PeriodicalId":206778,"journal":{"name":"2017 13th International Conference on Advanced Technologies, Systems and Services in Telecommunications (TELSIKS)","volume":"152 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":"127313353","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}

Their principles, however, were often applicable to radio transmission as well. This paper gives a short overview of the basic patents applicable to radio engineering. In addition, the paper provides a comment on the radio patent dispute with Marconi which was posthumously won by Tesla.","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":"129210750","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 developed differential model is well-posed, admitting a unique and weak solution that is computed by using a robust finite difference-based numerical approximation scheme.
