In this paper, we are going consider the decision feedback algorithm with reduced analysis interval, which allows to increase the performance of the detector almost without increasing computational complexity. This algorithm has already been used for detection of Faster than Nyquist (FTN) signals with BPSK modulation, but now it is proposed to apply it to QAM modulation. It is shown that this algorithm provides larger energy gains in conditions of more severe ISI. The energy losses relative to the theoretical BER performance are estimated for FTN signals with QAM-4 and QAM-16 transmitted at symbol rate increased by 11% and 25%.","PeriodicalId":204076,"journal":{"name":"2022 International Conference on Electrical Engineering and Photonics (EExPolytech)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125130446","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}

Chemotherapy and radiation have a very poor prognosis for individuals with advanced non-small cell lung cancer (NSCLC). Early identification of lung cancer is critical, and excessive detection delay or triggering lung cancer instances may result in the patient's affliction, which may explain the prompt execution and efficacy of diagnostic and therapeutic operations. Currently, therapeutic methods for lung cancer are based on the morphological type of tumors and require more research. The eventual goal of this work is to discover new markers for therapy and to customize therapy based on CT image and an individual tumor genetic composition using computer methods. Our method distinguishes Adenocarcinoma from Squamous cell carcinoma which helps physicians in initial detection of lung cancer type. As a result, the proposed method distinguished these types of NSCLC by accuracy of 90%.","PeriodicalId":204076,"journal":{"name":"2022 International Conference on Electrical Engineering and Photonics (EExPolytech)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114297621","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 drawback of RRC pulses is high peak-to-average power ratio (PAPR). One of the ways to reduce the PAPR is to apply Faster-than-Nyquist (FTN) signaling. In this paper we compare PAPR and energy efficiency of FTN and Nyquist signals under conditions of the same spectral efficiency. With the help of simulation modeling it is shown that for certain values of roll-off factor FTN signals based on RRC pulses can provide about 1 dB gain in PAPR. It is also possible to achieve the gain in bit error rate (BER) for the case of FTN with QAM-16 compared to Nyquist signals with QAM-32 when decision feedback algorithm is used.","PeriodicalId":204076,"journal":{"name":"2022 International Conference on Electrical Engineering and Photonics (EExPolytech)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116306656","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}

Power amplifiers tend to work in a stable condition relatively, where the loop gain is also stationary. However, in a situation of incomplete power input, the transmitted signal becomes unstable, its amplitude increasing and decreasing rapidly. Such violent change in the signal will make the power amplifiers and other analog devices work in unstable conditions. One of the results is that the loop gain will be changed quickly corresponding to the change of the signal amplitude. In this paper, we proposed an adaptive algorithm with changeable learning rate to replace Least Square to get better estimation of loop gain.","PeriodicalId":204076,"journal":{"name":"2022 International Conference on Electrical Engineering and Photonics (EExPolytech)","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124796987","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}
