The proposed concept lays its foundations on series-cascaded multi-band stages, each of them shaped by two identical transversal multi-resonant cells. The transfer function characteristics of each band are tuned by a pair of resonators in each cell that control the center frequency, bandwidth (BW), and mode of operation—bandpass or all-reject—. The overall BPF exhibits a multi-band transfer function with 1-to-N bands that can be independently tuned in terms of frequency, BW, and number. The operating principles of this multi-passband filter concept are demonstrated through simulated examples of a quad-band BPF and the measurement of a tri-band microstrip prototype.","PeriodicalId":184822,"journal":{"name":"2020 IEEE Radio and Wireless Symposium (RWS)","volume":"1 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":"126722855","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}

Taking advantage of this phenomenon the movement of a nonlinear target can be monitored and distinguished from background clutter. This paper discusses the use of an intermodulation radar, operating in the 5.8-GHz ISM band, and a passive nonlinear tag, located on the wrist, to monitor human vital signs and more specifically to improve remote monitoring of the heart rate. The non-ideal background clutter rejection of an intermodulation radar allowed for the respiration rate to also be monitored. Since the movement of the chest reflects the two individual tones from the transmitter and not the third order intermodulation frequency, for which the receiver is tuned, the respiratory frequency component has a scaled amplitude in comparison to what is seen with the use of a Doppler radar. This prevents the heart rate from being indistinguishable from the harmonics of the respiration.","PeriodicalId":184822,"journal":{"name":"2020 IEEE Radio and Wireless Symposium (RWS)","volume":"288 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":"116872207","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}

While the focus of Release 15 was enhanced mobile broadband (eMBB) services, Release 16 features are concurrently being developed to add or enhance services based on Release 15. Notable Release 16 features include ultra-reliable and low-latency connection (URLLC), NR vehicle-to-X (V2X), NR on unlicensed bands (NR-U), and integrated access and backhaul (IAB). In particular, IAB enables backhaul connectivity, without expensive fiber deployment, for fast, cost-effective, and dense millimeter-wave (mmWave) deployments. This paper examines Release 16 features and considers a link simulation of a 28 GHz NR IAB node using an 8x8 phased-array antenna. The phased-array radiation pattern is extracted through electromagnetic (EM) simulation and combined with NR link simulation. Bit-error rate (BER) is used to evaluate the link performance operating as an IAB node subjected to an interferer.","PeriodicalId":184822,"journal":{"name":"2020 IEEE Radio and Wireless Symposium (RWS)","volume":"1 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":"124649974","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}
