The conflict between communications and sensing is analyzed in terms of bandwidth and power, for frequency modulation waveforms originally used in radar sensing. It is found that, when the communication receiver is also the sensing target, the bandwidth is approximately partitioned between communications and sensing, thus making an almost zero-sum game between communications and sensing. The same conclusion for bandwidth conflict still holds when the communication receiver and target are separated. The feasible region and trade-off boundary of JCS are obtained from numerical computations.","PeriodicalId":424479,"journal":{"name":"2022 2nd IEEE International Symposium on Joint Communications & Sensing (JC&S)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117135962","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 is implemented via a low complexity analog architecture, constituted by a phase shifting network and variable gain amplifier. The proposed system exploits the multiple antenna transmitter for the simultaneous communication with multiple downlink users and radar target detection. The transmit waveform of the proposed JRC system is designed to minimize the downlink multi-user interference such that the desired radar beampattern is achieved and the architecture specific constraints are satisfied. The resulting optimization problem is non-convex and in general difficult to solve. We propose an efficient algorithmic solution based on the primal-dual framework. The numerical results show enhanced performance of the proposed approach when compared to existing state-of-the-art fully-digital method.","PeriodicalId":424479,"journal":{"name":"2022 2nd IEEE International Symposium on Joint Communications & Sensing (JC&S)","volume":"138 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121958976","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 paper, we propose a machine learning based LAI assisted codeword selection algorithm. Specifically, based on the spatial consistency of mmWave channel, we transform the codeword selection problem into a nonlinear classification problem with the LAI of the user equipment (UE). Furthermore, we derive the relationship between the LAI of UE and the arrival angles of the line-of-sight (LOS) path. To solve this nonlinear classification problem, a custom kernel function based on the definition of linearly separable sample space is proposed for the support vectors machine (SVM) method. Finally, simulation results are presented to show the effectiveness of the proposed algorithms.","PeriodicalId":424479,"journal":{"name":"2022 2nd IEEE International Symposium on Joint Communications & Sensing (JC&S)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123918584","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}

Simple methods relying on cross-correlation (CCR) only have limited estimation accuracy by the inverse of the probing signal bandwidth. In this paper, we experimentally validate a superresolution path delay estimation (SPDE) method, which provides better accuracy than the CCR-based methods. For this purpose, we employ a radar setup using two collocated 26 GHz radio front-ends for transmission and reception. In a particular scenario, we consider a channel with two rays corresponding to cross talk and a target of interest. We show that the estimated delays using SPDE match the target distance with high accuracy using narrower bandwidth where CCR fails. Since the employed front-ends is primarily developed for communication, our setup is a showcase of reusing the hardware for joint radio communications and sensing (JCAS).","PeriodicalId":424479,"journal":{"name":"2022 2nd IEEE International Symposium on Joint Communications & Sensing (JC&S)","volume":"1 17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127981426","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}

This is possible because, unlike with cyclic-prefix OFDM (CP-OFDM) radar, ZP-OFDM radar does not need full duplexing, as there is no self-interference during the guard interval (GI), which can be used for radar detection. We derive the required receiver signal processing for radar detection in that case, and show that when the self-interference in CP-OFDM JC&S is high, the ZP-OFDM is beneficial. This advantage depends on the target distance, because it influences the relative amount of energy from the reflected energy that can be captured in the GI. We show then that ZP-OFDM can be a cost-effective and efficient alternative to CP-OFDM under certain conditions.","PeriodicalId":424479,"journal":{"name":"2022 2nd IEEE International Symposium on Joint Communications & Sensing (JC&S)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117233641","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}

There exists a significant body of research that uses the channel state information (CSI) reported by wireless network interface cards for sensing, but only the amplitude and phase difference of the CSI between receiver antennas are processed. The raw phase of the CSI is contaminated by the carrier frequency offset, packet detection delay and other hardware imperfections, so it is too noisy to use. Our work introduces the raw phase of CSI into sensing by synchronizing the transmitter and receiver clocks to remove carrier frequency offset and using a new method to remove packet detection delay. We validate our design in a real-world scenario to detect breathing and walking and demonstrate that the raw phase of the CSI offers an evident improvement in Wi-Fi CSI-based sensing. Additionally, we are the first to use the Raspberry Pi and ATH9k wireless network interface card together for CSI data collection, which is cheap, portable and versatile.","PeriodicalId":424479,"journal":{"name":"2022 2nd IEEE International Symposium on Joint Communications & Sensing (JC&S)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127094706","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}

Several state-of-the-art superresolution path delay estimation (SPDE) approaches have been proposed to provide more precise PDE based on eigendecomposition. Although superresolution techniques reduce the bandwidth requirement on the sensor, the achievable resolution is still limited. The resolution can be further improved when measurements on different frequency bands are combined. In this paper, we propose an approach to combine the frequency-domain channel estimates on different nonconsecutive frequency bands to provide a better resolution for the PDE.
