A machine-learning approach is explored for obtaining artificial intelligence (AI)-based digital twins of various types, including traditional (shallow) neural networks, deep belief networks, and deep convolutional networks for supervised learning, as well as reinforcement learning approaches. While several related approaches exist in the literature, they have generally been limited to simulations. By contrast, the goal of this work is to study the performance of state-of-art machine learning algorithms in an experimental framework using real-world test data obtained from a recently completed STAR front-end [1] . The proposed STAR front-end has measured bandwidths of better than 500 MHz across al-3 GHz range and provides better than 80 dB analog cancellation of self-interference. A dataset of experimental measurements of this front-end will be collected and applied to a suite of ML algorithms for self-interference cancellation that has recently appeared in the literature. The machine learning algorithms will be evaluated for performance in terms of computational complexity, latency, power consumption, and the reduction of self-interference from the transmitter into the receiver during STAR operation.","PeriodicalId":253455,"journal":{"name":"2021 IEEE-APS Topical Conference on Antennas and Propagation in Wireless Communications (APWC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130845496","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 orthgogonality of OAM modes leads to azimuth localization of multiple targets. A pulsed radar architecture based on phased array (PA) positioned along the z axis (zPA) with VW uniform circular array (UCA) as its elements is described for simultaneous range, polar and azimuth angular localizations of radar targets. The zPA is focused to the peaks of VW patterns for narrow beams and low side lobes. For angular localization of targets in the same range-Doppler cell, an intrapulse multiple transmit (TX) and multiple receive (RX) scheme associated with multiple p’s is described. The radar pulse is divided into subpulses as many as the maximum value of p. In each subpulse, we TX by p and RX with ± p. The range(r) localization, which uses (-p) RX, is based on the intrapulse topological charge and polyphase code pulse compression by cross-correlation RX. The multiple elevation (polar –ϑ) localization, which also uses (-p)RX, is based on monopulse processing of the highest signal-to-noise ratio responses. The azimuth (φ) localization pertinent to each ϑ uses (+p) RX and form a transform in φ domain. A full PA using UCA and zPA in RX is also described to increase the accuracy of the angular localizations. The elements of UCA are highly 9 symmetrical microstrip circular patch elements An S band radar example is given to assess the performance of the localization algorithms.","PeriodicalId":253455,"journal":{"name":"2021 IEEE-APS Topical Conference on Antennas and Propagation in Wireless Communications (APWC)","volume":"51 Suppl 53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126899724","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}

Almost all DFL algorithms require an initial calibration procedure to estimate the electromagnetic (EM) effects induced by the environment. Calibration includes fingerprinting RF signal acquisitions or other on-field measurements to estimate the parameters of the radio propagation model adopted for data processing. This calibration phase is typically time consuming, error-prone and difficult to be fully automatized. In addition, changes or modifications in the layout of the wireless network require a recalibration stage to maintain good localization performances. In this paper, we propose a novel calibration technique based on physical radio propagation models. For an assigned deployment of the anchor nodes, the proposed calibration scheme is designed to estimate the geometrical and the EM propagation parameters of the scenario and their effects on the localization accuracy. The proposed calibration scheme paves the way to a fully automatized system for DFL applications based on EM propagation models.","PeriodicalId":253455,"journal":{"name":"2021 IEEE-APS Topical Conference on Antennas and Propagation in Wireless Communications (APWC)","volume":"141 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123476432","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}
