The recently developed orthogonal time frequency space (OTFS) waveform which relies on delay Doppler domain for information transmission, can reveal the physical wireless propagation environments. In this paper, we consider the environment sensing problem solely based on OTFS communications. In particular, the delay and Doppler indices attracted from OTFS channel estimation can be converted to path range distance and relative speed, on which we develop an elliptical positioning algorithm to accurately determine the target location and the receiver velocity. Simulation results verify the effectiveness of the delay Doppler communications-assisted sensing framework.","PeriodicalId":158152,"journal":{"name":"2023 IEEE 3rd International Symposium on Joint Communications & Sensing (JC&S)","volume":"230 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115751047","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 problem is important in the context of integrating radar into collocated communication systems since the hardware must be able to accommodate full-duplex and the associated spillover without saturating. The concept of beamforming cancellation is adopted and a design suited for beamforming codebooks is formulated based on the peak to sidelobe ratio objective and a peak power and signal-to-noise ratio constraint. The performance is demonstrated numerically with non-ideal hardware models, where we show the feasibility of using beamforming codebooks for simultaneous beamsteering and cancellation of strong spillover signals.","PeriodicalId":158152,"journal":{"name":"2023 IEEE 3rd International Symposium on Joint Communications & Sensing (JC&S)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128510415","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 the context of densely deployed JCS networks, such as in VANETs, the interference from multiple JCS transceivers may significantly impair the performances of communications and sensing. Due to the large bandwidth required for radar sensing, it is difficult to assure orthogonal channel access in JCS. Therefore, spectrum spreading is a promising solution to the interference mitigation, similarly to code division multiple access (CDMA), modulated by communication symbols. Then, the design of waveform is to optimize the ambiguity function (AF) and cross AF (CAF), such that the sensing performance is improved while the interference is mitigated. The key difference from traditional sensing waveform synthesis is the randomness incurred by the communication modulation. Therefore, the variances of AF and CAF are taken into account of waveform synthesis, whose performances are demonstrated by numerical simulations.","PeriodicalId":158152,"journal":{"name":"2023 IEEE 3rd International Symposium on Joint Communications & Sensing (JC&S)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121711921","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, we consider a state-dependent binary-input two-user additive white Gaussian noise (AWGN) broadcast channel, in which the channel state se-quence consists of two components, each affecting a receiver, mod-eled as independent and identically distributed (i.i.d.) correlated phase shifts to approximate the location-dependent signatures of the receivers. The objective of the transmitter is to simultaneously estimate the channel states while reliably transmitting a secret message to one of the receivers, treating the other as a passive attacker. We characterize the exact secrecy-distortion region when 1) the channel output feedback is perfect, i.e., noiseless with a unit time delay; and 2) the channel is degraded. The characterized rate region offers an outer bound for more complex secure ISAC settings with noisy generalized output feedback and non-degraded channels. We also characterize the secrecy-distortion region for reversely-degraded channels. The results illustrate the benefits of jointly sensing the channel state and securely communicating messages as compared to separation-based methods.","PeriodicalId":158152,"journal":{"name":"2023 IEEE 3rd International Symposium on Joint Communications & Sensing (JC&S)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125464095","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, the radar processing at the PWR largely depends on the Wi-Fi signal and its characteristics. In the latest amendment of the Wi-Fi standard, namely 802.11ax, Multi-User Multiple-Input Multiple-Output (MU-MIMO) technology is used to improve the spatial efficiency of the wireless channel by precoding the transmitted signal for each user. However, from the PWR perspective, precoding affects the signal power that illuminates a given target depending on its Angle-of-Departure (AoD). In this paper, we first quantify the impact of precoded signals on PWR processing. Then, we show that it is possible to recover the AoD of well-illuminated targets by using a PWR equipped with a single-antenna. To do so, a three-step-scheme, which works by exploiting the MU-MIMO synchronization and precoded signal transmission, is proposed. The accuracy of the proposed method, as well as its shortcomings are shown through numerical analyses.","PeriodicalId":158152,"journal":{"name":"2023 IEEE 3rd International Symposium on Joint Communications & Sensing (JC&S)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134164650","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 spreading gain, which equals the ratio between the Fourier bandwidth and Shannon bandwidth, determines the communication data rate, interference power and the randomness in the sensing performance. Therefore, a coding-spreading trade-off exists for the compromise between communications and sensing.

Compared to traditional UWB antennas using a thick substrate and circular/elliptical patch, this paper utilises an alternative approach by using a rectangular patch with the finite slotted ground on a 0.508 mm thick RO4003 substrate. A systematic approach is presented for the determination of the slot's position in each step of the DGS method to increase the bandwidth of the narrowband rectangular patch antenna. An equivalent circuit model is also characterized based on the Foster canonical form theorem for the UWB antenna. The fabricated antenna (31.5mm $mathrm{x} boldsymbol{33.5}$ mm) has a bandwidth of 7.9 GHz (3.8-11.7 GHz) with a peak gain of 6 dBi and 90% efficiency in the operating frequency range. Additionally, communication and range measurements are performed to show the future application scenarios like joint communication and sensing (JC&S). Easy identification of the slot position using current distribution for bandwidth enhancement, an equivalent circuit model for simpler theoretical analysis, and experimental system validation of the developed UWB antenna are the highlights of this paper.","PeriodicalId":158152,"journal":{"name":"2023 IEEE 3rd International Symposium on Joint Communications & Sensing (JC&S)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131001038","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}

REMs are an essential tool for spectrum monitoring which becomes more and more important as the spectrum is a bottleneck in today's wireless networks. The paper proposes a machine learning (ML)-based approach that combines knowledge from a distributed sensor network and knowledge on obstacles to create an REM without requiring knowledge on the transmitter location. The proposed approach is evaluated and compared against two other methods based on simulated data for different sensor grid sizes. In the case of a sparse sensing network, the approach outperforms Kriging as well as an ML-based approach that only uses received power data.

Joint communication and sensing (JC&S) and in-band full duplex (IBFD) communications provide opportunities of spectrum reuse. IBFD communication hardware requires high transmitter-to-receiver (TRx) isolation, making it shareable and reusable with mono-static continuous wave radar in JC&S context. On the other hand, design and development of beamforming phased arrays, required for communication coverage and radar spatial filtering, becomes challenging when a high TRx isolation assurance is required. This paper presents a solution in the form of antenna-duplexed passive beamformer usable for IBFD communication and mono-static continuous wave radars, mitigating two key challenges/requirements of JC&S hardware reuse in co-design approach - TRx isolation and beamforming capability.
