Namely, transmit diversity is achieved here by using a hybrid beamforming technique to establish recovery beams in Rician channels. Once the direct line-of-sight link is blocked, equal gain combining is applied to the incoming signals from the dual-beams, i.e., to compensate for signal degradation. The proposed method provides near-instantaneous link recovery without the need for iterative beam scanning. Simulations show that the proposed method yields enhanced received signal levels across various blockage parameters versus single beam recovery schemes.","PeriodicalId":193359,"journal":{"name":"2018 IEEE 19th Wireless and Microwave Technology Conference (WAMICON)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125779917","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}

We propose a novel analog self-interference cancellation technique for single antenna IBFD systems. In this technique, we use the secondary SI signal reflected by the antenna to cancel the primary SI signal leaked from the circulator transmitter port at the receiver. We use an adjustable mismatch impedance terminal (IMT) at the antenna port to modify the magnitude and phase of the secondary SI signal. We design and fabricate a prototype of single antenna IBFD in the ISM frequency band at 900 MHz. The measurement results show 40 dB SI cancellation over 35 MHz frequency bandwidth.","PeriodicalId":193359,"journal":{"name":"2018 IEEE 19th Wireless and Microwave Technology Conference (WAMICON)","volume":"272 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122768830","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 linearity performance can be increased by splitting the output stage, which has a gate periphery of 2.5mm, into two parts of 1.25mm each and optimizing their bias. Biasing the two FETs differently leads to phase cancellation of IMD3 components and improvement in OIP3 performance. The experimental results show up to 9.5dBm of improvement in the OIP3 when one gate is biased in Class AB and the other is in deep Class AB mode. Linearity FOM (OIP3/Pdc) is also improved, reaching up to 14 at higher Pouts.","PeriodicalId":193359,"journal":{"name":"2018 IEEE 19th Wireless and Microwave Technology Conference (WAMICON)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126458595","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 advent of non-semiconductor switch technology, such as MEMS, has spurred further research in unconventional switch technology for mmWaves. Recently, it has been shown that vanadium dioxide, a thermochromic material whose resistance changes with temperature, could provide a path forward in developing reconfigurable mmWave devices. As an initial step towards this vision, we investigate the integration of vanadium dioxide switches in reconfigurable components at 15 GHz. In particular, a frequency reconfigurable antenna and a reconfigurable phase shifter are shown. The low loss and minimal parasitics of vanadium dioxide technology have the potential to enable devices at 15 GHz and beyond.","PeriodicalId":193359,"journal":{"name":"2018 IEEE 19th Wireless and Microwave Technology Conference (WAMICON)","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116418549","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}

Such networks are expected to be common in the IoT segment of 5G networks and our methodology may be extended to other network configurations. Our results show that the amount of interference that can be tolerated depends on the node density of a Poisson point process and the transmission power. Moreover, decreasing the number of pulses per burst while transmitting a bit may increase the interference tolerance. On the other hand, UWB WBANs cannot tolerate significant amounts of interference in networks of ultra-densely deployed nodes. In these situations, there will be a significant amount of inter-network interference, and it is essential to adjust the power levels of all the nodes. With this objective, the transmission power of all nodes is decreased and their levels are determined by using a game theoretical approach; specifically with a non-cooperative continuous-kernel game. These optimized power levels not only reduce interference but also enhance the energy efficiency, which is of critical importance for WBANs.","PeriodicalId":193359,"journal":{"name":"2018 IEEE 19th Wireless and Microwave Technology Conference (WAMICON)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121108133","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}
