Demodulation algorithms described in this article proposed for fixing bit-error rate (BER) degradation of received signal caused by inter-channel interference (ICI). Comparison of symmetrical, asymmetrical and standard demodulation algorithms was considered. Crossing points of iterative algorithms and standard algorithm, dependences of values of crossing points on number of subcarriers in signal, subcarriers used for feedback algorithm and factor of compressed bandwidth in order to evaluate efficiency limits of iterative feedback algorithm for subsequent use in signal-coding systems. It was shown that max value of crossing point when improving algorithm can give benefit with chosen parameters is 20.6 dB. Value of crossing point is the lowest when number of subcarriers in signal is the lowest, factor of compressed bandwidth is close to 1 and number of subcarriers used for feedback is large.

The design of the second sensor is a multimode optical fiber coated on one edge with a photoactive compound. With a properly selected concentration of substances in the photoactive composition, it is possible to obtain the optical signal for the wavelength in range from 425 to 440 nm, which corresponds to the wavelength of the photoluminescence emission of selected phosphor. The prospects of using the developed structures as sensors for ultraviolet radiation of the A range are confirmed by the presence of photoluminescence at the output end upon excitation with a wavelength in the range of 365–390 nm and a linear dependence of the output amplitude of optical signal at optical power launched to the fiber input.","PeriodicalId":204076,"journal":{"name":"2022 International Conference on Electrical Engineering and Photonics (EExPolytech)","volume":"52 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":"127861211","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}

It offers a micron-scale spatial resolution, which is sufficient for many applications, but still some improvement is highly anticipated. However, when traditional signal processing methods are used, axial spatial resolution is inversely proportional to the spectral width, in which the measurement is performed. We propose to apply MUSIC algorithm for processing OCT interference signals and demonstrate that several-fold improvement of axial spatial resolution can be achieved under certain conditions.","PeriodicalId":204076,"journal":{"name":"2022 International Conference on Electrical Engineering and Photonics (EExPolytech)","volume":"27 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":"126306940","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}
