Further approaching the Shannon limit that determines the channel throughput is related to increasing the size of the signal constellation. However, an increase in the size of the signal constellation results in sharp growth of energy losses for FTN signals. To reduce these energy losses optimal FTN pulses obtained as a result of solving the optimization problem with the constraint on signal constellation size M may be used. In this work, optimal pulse shapes for pulse-amplitude modulation (PAM) with M=4, 16, 64, 256 were found. It was shown that applying optimal FTN signals with PAM allows reducing energy losses by 4 dB regarding the FTN signals based on root-raised-cosine pulses for coherent symbol-by-symbol detection algorithm. In terms of approaching the Shannon limit, the closest results are provided by determining the bandwidth containing 99% of signal energy.","PeriodicalId":305685,"journal":{"name":"2019 IEEE International Conference on Electrical Engineering and Photonics (EExPolytech)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128102694","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}

Both approaches involve a number of practical difficulties. In the case of application of the window functions, the complexity of the spectrum measurement algorithm increases. In this case a decrease in the measurement error of the spectral components is achieved by increasing the measurement error of the fundamental spectral component. When using SRC an additional operations are required to measure the frequency of the signal and to make digital interpolation. In this case, the task of analyzing the resulting measurement error is substantially complicated. In the present work, an analysis of the measurement error of the amplitude spectrum by using a sliding discrete Fourier transform is performed. A method is proposed that allows to reduce the measurement error of the amplitude spectrum by applying output filtration of the measurement results of the amplitude spectrum. The obtained analytical relations allows to estimate the measurement error of the amplitude spectrum. Requirements have been developed for an additional filter that provides filtration of the measurement signal of the amplitude spectrum. By using the Simulink software package, a simulation model of the proposed measurement method is performed. The reliability of the obtained expressions is confirmed by comparing the results which are obtained by the analytical relationships and by the simulation model.","PeriodicalId":305685,"journal":{"name":"2019 IEEE International Conference on Electrical Engineering and Photonics (EExPolytech)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129726247","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}
