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…
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…
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…
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…
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…
