Optimally Deployed Multistatic OTFS-ISAC Design With Kalman-Based Tracking of Targets
Jyotsna Rani, Kuntal Deka, Ganesh Prasad +1
This paper studies orthogonal time-frequency space (OTFS) modulation aided multistatic integrated sensing and communication (ISAC) in vehicular networks, whereby its delay-Doppler…
An Explicit Upper Bound of Generalized Quadratic Gauss Sums and Its Applications for Asymptotically Optimal Aperiodic Polyphase Sequence Design
Huaning Liu, Zilong Liu
This work is motivated by the long-standing open problem of designing asymptotically order-optimal aperiodic polyphase sequence sets with respect to the celebrated Welch bound. Att…
Doppler-Resilient LEO Satellite OFDM Transmission with Affine Frequency Domain Pilot
Shuntian Tang, Xiaomei Wu, Xinyi Wang +5
Orthogonal frequency division multiplexing (OFDM) based low Earth orbit (LEO) satellite communication system suffers from severe Doppler shifts, while {the Doppler-resilient affine…
Vehicular Multistatic OTFS-ISAC: A Geometry-Aware Deployment and Kalman-Based Tracking
Jyotsna Rani, Kuntal Deka, Ganesh Prasad +1
Integrated sensing and communication (ISAC) is a promising paradigm for next-generation vehicular networks, yet existing orthogonal frequency-division multiplexing (OFDM)-based des…
Local Ambiguity Shaping for Doppler-Resilient Sequences Under Spectral and PAPR Constraints
Shi He, Lingsheng Meng, Yao Ge +3
This paper focuses on designing Doppler-resilient sequences with low local Ambiguity Function (AF) sidelobes, subject to certain spectral and Peak-to-Average Power Ratio (PAPR) con…
Hybrid Rate-Splitting and Sparse Code Multiple Access (RS-SCMA): Design and Performance
Minerva Priyadarsini, Zilong Liu, Kuntal Deka +2
This paper proposes, for the first time, a hybrid multiple access framework that integrates the principles of rate-splitting (RS) and sparse code multiple access (SCMA) in an SISO…
