The advantage of the SM consists in using only one RF (Radio Frequency) chain in the transmitting end which helps to increase the energy efficiency and the performance of the transmission. The related work in the literature is mostly based on the study of the SM transmission under the simple channel models. Moreover, it is assumed that the perfect Channel State Information (CSI) is known by the receiving end. This article discusses a CSI detector for the channel estimation and analyzes the performance of the proposed system over the time-varying Rician fading channel. The ADS-Matlab co-simulation results demonstrate that the bit error rate (BER) can be kept at an acceptable level with a realistic CSI detector, and in this case the system offers better performance with a small Rician factor.","PeriodicalId":184822,"journal":{"name":"2020 IEEE Radio and Wireless Symposium (RWS)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130538785","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 comprises a monopole printed on the top face of a substrate that is acting as a driving element, and two other parasitic elements placed symmetrically on the two sides of a partial ground plane. The parasitic elements are interchanged to be a reflector or a director. To achieve pattern reconfiguration, the approach of Yagi-Uda configuration is employed, where the positions of the reflector and director are to be interchanged using DC-controlled electronic switches. Four scanning angles (-90°, 0°, 90° and 180°) around the operating frequency of 4.3 GHz are accomplished. Also, an acceptable impedance matching in all switching schemes is achieved.","PeriodicalId":184822,"journal":{"name":"2020 IEEE Radio and Wireless Symposium (RWS)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123388319","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}

Our chip generates and radiates 1.9 ps pulses with an on-chip antenna at a repetition rate of 5.2 GHz, resulting in a broadband 0.1-1.1 THz frequency comb. A specular non-lineof-sight link was created using the impulse radiator, parabolic reflector antennas, a plane mirror, and a downconverting mixer. The THz channel was characterized up to a distance of 113 m. The measurement results demonstrate channel path loss, atmospheric absorption, and low-loss frequency windows suitable for wireless links in this range. To the best of authors’ knowledge, this is the first time a custom lowpower silicon-based radiator has been used as the source in channel characterization at THz frequencies.","PeriodicalId":184822,"journal":{"name":"2020 IEEE Radio and Wireless Symposium (RWS)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114949304","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}

In this work, we investigated identity authentication of patients with OSA symptoms based on extracting respiratory features (peak power spectral density, packing density and linear envelop error) from radar captured paradoxical breathing patterns in a small-scale clinical sleep study integrating three different machine learning classifiers (Support Vector Machine (SVM), K-nearest neighbor (KNN), Random forest).

This paper investigates different adaptive learning rate functions as well as starting locations for a multi-dimensional gradient-descent algorithm.

This makes it possible to measure microwave structures with different port types. The one degree of freedom uncertainty of the error boxes, which is inherent to the TRL calibration procedure, is removed by the assumption that these boxes represent reciprocal devices. This is the case in most practical applications.
