Optimal Interference Exploitation Waveform Design with Relaxed Block-Level Power Constraints
Xiao Tong, Lei Lei, Ang Li +2
This paper investigates constructive interference (CI)-based waveform design for phase shift keying and quadrature amplitude modulation symbols under relaxed block-level power cons…
Channel Estimation for RIS-Aided MU-MIMO mmWave Systems with Practical Hybrid Architecture
Liuchang Zhuo, Cunhua Pan, Hong Ren +4
This paper proposes a correlation-based three-stage channel estimation strategy with low pilot overhead for reconfigurable intelligent surface (RIS)-aided millimeter wave (mmWave)…
Optimality of the Bussgang Linear MMSE Channel Estimator for MIMO Systems with 1-Bit ADCs
Minhua Ding, Italo Atzeni, Antti Tölli +1
In this paper, we study the optimality of the Bussgang linear minimum mean squared error (BLMMSE) channel estimator for multiple-input multiple-output systems with 1-bit analog-to-…
Enhanced Automotive Radar Collaborative Sensing By Exploiting Constructive Interference
Lifan Xu, Shunqiao Sun, A. Lee Swindlehurst
Automotive radar emerges as a crucial sensor for autonomous vehicle perception. As more cars are equipped radars, radar interference is an unavoidable challenge. Unlike conventiona…
Integrated Sensing and Communication Under DISCO Physical-Layer Jamming Attacks
Huan Huang, Hongliang Zhang, Weidong Mei +4
Integrated sensing and communication (ISAC) systems traditionally presuppose that sensing and communication (S&C) channels remain approximately constant during their coherence time…
Feature Allocation for Semantic Communication with Space-Time Importance Awareness
Kequan Zhou, Guangyi Zhang, Yunlong Cai +3
In the realm of semantic communication, the significance of encoded features can vary, while wireless channels are known to exhibit fluctuations across multiple subchannels in diff…
