IRS-Assisted Joint Sensing and Communication Design for Autonomous Driving

ICASSP 2024accepted

Joint sensing and communication (JSAC) has emerged as a promising technology in autonomous driving, as it allows simultaneous road sensing and two-way communication using a single shared platform. Meanwhile, intelligent reflective surface (IRS) enables sensing enhancement and communication with targ…

Weak Target Detection in Massive MIMO Radar via an Improved Reinforcement Learning Approach

ICASSP 2022accepted

Massive multi-input-multi-output (MMIMO) cognitive radar can enhance the target detection ability in a dynamic environment via a continuous "perception-action" cycle. In our previous work, we proposed a reinforcement learning (RL) based approach for multi-target detection in MMIMO. However, this met…

Sparse Array Transceiver Design for Enhanced Adaptive Beamforming in MIMO Radar

ICASSP 2021accepted

Sparse array design aided by emerging fast sensor switching technologies can lower the overall system overhead by reducing the number of expensive transceiver chains. In this paper, we examine the active sparse array design enabling the maximum signal to interference plus noise ratio (MaxSINR) beamf…
