The radar uses a multiplier/amplifier chain to achieve the desired signal at E-band from a source at X-band. It is shown that this filter can provide more than 50 dB signal suppression at 72 GHz (7th harmonic) and 35 dB suppression at 85.5 GHz (9th harmonic) with less than 1 dB ripples in the pass-band and less than 500 ps group delay. The filter is made of a perforated septum placed in the E-plane of a rectangular waveguide. Fabrication error was successfully minimized by using a brass sheet and a high precision laser cutter. This high-performance filter is shown to improve the performance of the FMCW MMW radar by significantly lowering the noise floor and eliminating other interference effects.","PeriodicalId":443426,"journal":{"name":"2020 IEEE USNC-CNC-URSI North American Radio Science Meeting (Joint with AP-S Symposium)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123359770","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}

Specifically, in underlay mode, D2D communications optimize for maximizing the corresponding utility under cellular users' quality of service (QoS) requirement and transmit power constraints. To solve this challenging subchannel allocation problem, which is actually a nonconvex mixed-integer programming problem, we decompose the whole optimization problem into independent subproblems. Firstly, we find out the candidate D2D communications users who are permitted to share the same spectrum with cellular users in the admission control subproblem. Then, to solve the resource allocation subproblem, a novel fast and tradeoff subchannel allocation algorithm between utility and fairness is proposed with setting higher priority for unpopular D2D users. Simulation results validate our proposed novel fast allocation strategy achieves remarkable improvement with low complexity and fairness guaranteeing.","PeriodicalId":443426,"journal":{"name":"2020 IEEE USNC-CNC-URSI North American Radio Science Meeting (Joint with AP-S Symposium)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126223725","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}

Each column of unit cells on the metasurface can be independently, temporally modulated, allowing space-time modulation along one axis. The time-modulation of adjacent columns is staggered to establish a desired modulation wavenumber. A homogenized model of the metasurface is proposed that includes the discretization of the spatial modulation. Compared to the continuous spatial modulation commonly assumed in earlier works, the discretized modulation allows new phenomena such as subharmonic mixing. Specifically, when the reflection phase is a sawtooth function in time, subharmonic frequency translation can be achieved without additional filtering and mixing circuitry. Measurement results validating the theoretical findings are presented at 10 GHz.","PeriodicalId":443426,"journal":{"name":"2020 IEEE USNC-CNC-URSI North American Radio Science Meeting (Joint with AP-S Symposium)","volume":"27 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123779954","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 present a ranging system using two code-modulated tones generated on separate transceivers in software-defined radio for unambiguous high-accuracy localization of nodes in distributed antenna arrays. The best peak-to-sidelobe level was -0.89 dB with the code-modulated waveform compared to -0.11 dB for a standard two-tone waveform, each with a frequency separation of 10 MHz. This increased suppression, though minimal in a traditional radar detection sense, is significant for cooperative ranging between nodes in a distributed array. The code-modulated two-tone waveform achieved a range accuracy below 3 cm in a wireless ranging setup.","PeriodicalId":443426,"journal":{"name":"2020 IEEE USNC-CNC-URSI North American Radio Science Meeting (Joint with AP-S Symposium)","volume":"163 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134285282","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}
