The basis of these systems is the use of multisatellite constellations. Their practical realization requires solving numerous scientific and technical problems. One of the most painful problems is the problem of electromagnetic compatibility (EMC) between projected systems as well as between projected and operating satellite networks. The article shows that the realization of any of LEO-HTS systems results in a conflict situation in the radio frequency spectrum of the fixed-satellite and broadcasting-satellite services (Ku, Ka, Q/V bands). It is shown by the example of the analysis of EMC of LEO-HTS OneWeb and HEO-HTS Express-RV systems, the latter being oriented to servicing the Arctic regions in the Ku band, that to parry this conflict situation, a decrease in the capacity of subscriber radio links of the Express-RV system and/or an increase in the size of its subscriber antennas are required. The results of the analysis are presented for several geographical locations of subscriber terminals (from 60° N and more) and show that time intervals of interference action and C/I values depend considerably on their location in the Express-RV coverage area.","PeriodicalId":131975,"journal":{"name":"2018 Engineering and Telecommunication (EnT-MIPT)","volume":"16 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":"134443901","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 nature of the method is the decomposition of speech signals using the improved complete ensemble empirical mode decomposition with adaptive noise and formant analysis, namely, frequency and bandwidth measurement of the formant regions. A detailed mathematical description of decomposition varieties is presented, and a block diagram for the proposed method is given. The research of the method using the formed base of phonetically balanced speech signals registered in healthy people, and people under psycho-emotional disorders, both male and female, at the age of 18 to 79, is carried out. According to the results of the study, the developed method provides a high detection accuracy of psycho-emotional disorders: the first-kind error is 8.16%, and the second kind error is 5.66%.","PeriodicalId":131975,"journal":{"name":"2018 Engineering and Telecommunication (EnT-MIPT)","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":"125820313","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}

Natural generalization of LRC codes is LRC codes with availability in which each code symbol has more than one disjoint recovering set.

A numerical method for the optimal window synthesis with verification of the result is justified. Several window families with asymptotic sidelobe decay rates 6, 18, 30, and 42 decibels per octave along with some windows with higher decay rates are synthesized and their characteristics are provided. These window families contain familiar Hamming, Blackman–Harris, Nuttall, and Albrecht windows as particular cases. The windows designed have lower peak sidelobe levels than other known windows at a given main lobe bandwidth. An alternative representation of cosine-sum windows is proposed that allows a faster real-time implementation.","PeriodicalId":131975,"journal":{"name":"2018 Engineering and Telecommunication (EnT-MIPT)","volume":"78 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":"126461028","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}
