We can understand this because of their responsibility for the defects of these machines and the enormous losses and expenses that they generate. However, if it is true that many methods have been proposed, it must be said that a large part of them, although based on the stator current, does not focus on the only defect of the bearing as we propose through this work. In this study, our goal is to analyze the current induced in a copper coil placed side by side with magnets placed in the inner ring of the bearing, by the Machine Current Signature Analysis method in order to detect from the genesis any defect of the bearing. To do this we will apply algorithms such as Cuckoo Search-Support Vector machine, Convolutional Neural Network, Kernel-Principal Component Analysis, Recurrent Neural Network, and Support Vector Machine on the data extracted from this induced current using the Wavelet Transform technique in order to determine among these algorithms, which one would allow to detect in real time and with a good precision the defect of bearing when it occurs during the operation of the machine that incorporates it. The whole with an aim of developing, in combination with the embedded electronics an autonomous electronic system of detection of the defect of bearing in real time in an effective way.","PeriodicalId":426797,"journal":{"name":"2022 Workshop on Microwave Theory and Techniques in Wireless Communications (MTTW)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124172467","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}

This makes it possible to achieve very high data rates using OFDM signals with a large instantaneous bandwidth. These signals, however, have high PAPR values, which deteriorates the efficiency of power amplifiers due to large back-off values. At the same time, the development of GaN technologies allows high power levels to be achieved at base stations. This paper studies two back-off points using single carrier QPSK and 256QAM signals with a large instantaneous bandwidth. Taking advantage of specific features of the nonlinear behavior of GaN, the first back off is fixed as a function of the maximum power added efficiency (PAE). The second is set as a function of the 3dB compression point. The complexity and consumption of the linearization technique are taken into account when evaluating the performance of these back-offs. Experimental results show a 10-percentage-point increase of PAE without significant deterioration in the linearity and complexity/consumption of future DPD (Digital Predistortion) with the first back-off.","PeriodicalId":426797,"journal":{"name":"2022 Workshop on Microwave Theory and Techniques in Wireless Communications (MTTW)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114958427","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}

This field is developing very rapidly, and the essential part of it is collected data transmission to monitor and control different processes and physical parameters. In turn, this has increased the application of wireless sensor networks (WSNs) for different collected data transmission. Therefore, a need for safe communication approaches for WSN become an urgent problem. The study aims to create a system that offers a potential enhancement in the physical layer to fulfill the safe data transmission requirement. It is devoted to the frequency-modulated chaos shift keying (FM-CSK) communication system performance evaluation, which applies simulations and experiments for research, analysis, and comparison. For simulation, MATLAB environment and LTspice simulation software is used. The FM-CSK communication system prototype is developed for the experimental study using analog components. Study results are evaluated using the bit error ratio as performance estimation.","PeriodicalId":426797,"journal":{"name":"2022 Workshop on Microwave Theory and Techniques in Wireless Communications (MTTW)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122562713","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}
