The lack of unified design criterion prohibits gaining intuitions and unifying the mathematical structure in the analysis and design of JCS. This paper endeavors to unify both performance metrics of communications and sensing in either information-theoretic or estimation-theoretic framework. In the information-theoretic framework, the mutual information between the target and received signal, conditioned on the transmitted signal, is maximized while that of clutter and signal is minimized, which is formulated as an optimization problem. For the estimation-theoretic framework, the differential relationship between mutual information and minimum mean square error (MMSE) is leveraged to unify both communications and radar sensing in terms of MMSE. Both criteria are evaluated and compared using numerical simulations.","PeriodicalId":424479,"journal":{"name":"2022 2nd IEEE International Symposium on Joint Communications & Sensing (JC&S)","volume":"57 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":"116305155","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}

On the other hand, Wi-Fi, standardized under IEEE 802.11, has become the main gateway that connects devices to the internet. Recently, IEEE established the WLAN Sensing Task Group whose purpose is to study the feasibility of Wi-Fi-based environment sensing within the 802.11 framework, by combining radar and localization technologies. In the meantime, Multi-User Multiple-Input Multiple-Output (MU-MIMO) technology is introduced to the Wi-Fi standard. It is designed to improve the spatial efficiency of the wireless channel by simultaneously transmitting directive Wi-Fi signals to users. This paper aims at quantifying the impact of MU-MIMO signals on Passive Wi-Fi-based Radar-like sensing. First, based on the position of the client devices and the channel geometry, the radiation pattern of the AP is derived. While the wireless channel is illuminated by directive radio waves, the magnitude of the Poynting vector is obtained at a local point target, which then reflects the incident radio waves. Finally, the signal power seen by a sensing device is computed under the influence of a multipath channel. Our numerical analyses focus on an urban street, and we show that MU-MIMO can be seen as; i) an opportunity, since the vicinity of client devices are better illuminated, or ii) a threat, since the remaining parts of the street do not receive sufficient amount of power for channel sensing applications.","PeriodicalId":424479,"journal":{"name":"2022 2nd IEEE International Symposium on Joint Communications & Sensing (JC&S)","volume":"62 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":"121704475","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}

Therefore, classical approaches for system design based on digital signal processing are not a viable solution, but system design has to follow entirely new paradigms. In this regard, we present a sensory system with analog spike-based signal processing for sensing and communication, encoding the sensory information in the pulse repetition frequency (PRF), getting rid of energy hungry A/D and D/A conversion. Our spiking sensory system can generate spikes from any conventional analog output sensor using a compact, highly tunable voltage-controlled oscillator based on vanadium dioxide, and an analog differentiator circuit performing the transmit pulse shaping. The sole conversion from analog to digital takes place at the base station followed by the estimation of the PRF, for which we compare a conventional receiver design consisting of an analog-to-digital converter (ADC) with the use of an integrate-and-fire time encoding machine (IF-TEM). Results show the successful communication of sensory information from the edge node over an additive white Gaussian noise channel to the base station, with the IF-TEM outperforming the conventional ADC for a signal-to-noise ratio above 0 dB.","PeriodicalId":424479,"journal":{"name":"2022 2nd IEEE International Symposium on Joint Communications & Sensing (JC&S)","volume":"3 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":"129940819","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}

A fixed number of antennas in a rectangular configuration is allocable for the apertures, and we use a genetic algorithm to determine the allocation. We assume that the Tx aperture transmits one beam to an active communication user (downlink communication of time division duplex) and another beam for sensing the passive target, and the Rx aperture receives backscattered sensing signals simultaneously (full duplex). The array apertures' design criteria are based on the effect of interference mitigation when using linear beamforming. The optimal solution is determined when the side lobes for the beams are minimized at different scanning angles in the field of view. Our numerical results indicate that the near-optimal antenna allocation for the apertures does not perform uniformly for all desired beam directions, but yet, we could conclude a near-optimal solution based on the least discrepancy between the sidelobe suppression effects for the aperture patterns.","PeriodicalId":424479,"journal":{"name":"2022 2nd IEEE International Symposium on Joint Communications & Sensing (JC&S)","volume":"56 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":"114674214","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 model people with dieletric cylindrical shells with a thickness slightly higher than the electromagnetic skin depth. The electric field scattered by people is computed using the two-dimensional method of moments for electromagnetic scattering, accelerated using an iterative GMRES solver with Adaptive Cross Approximation and a block-Jacobi preconditionner. That scattered field is used to derive channel transfer functions that are combined to obtain a range-Doppler map. The presence of several ghost targets even in simple cases is highlighted, and could hinder people counting. When two people are aligned in front of the sensing-enabled Wi-Fi access point, the first blocking the line-of-sight of the second, it is shown that the field passing through the first person and reflected on the second person is sufficiently strong to detect it.

This includes a discussion of both challenges and requirements for location-aware applications in Intelligent Transportation Systems. Within this scope, a reproducible methodology for testing sensing and localization capabilities is derived and application scenarios are presented.

Emphasizing the challenges for creating such sensing networks, we introduce the required propagation properties for sensing and how they are leveraged. To compare the performance of the different sensing techniques, we analyze four commonly used metrics used in different fields and evaluate their advantages and disadvantages for sensing.
