Gaussian Arimoto-Blahut Algorithm for Capacity Region Calculation of Gaussian Vector Broadcast Channels
Tian Jiao, Yanlin Geng, Anthony Man-Cho So +2
This paper is concerned with the computation of the capacity region of a continuous, Gaussian vector broadcast channel (BC) with covariance matrix constraints. Since the decision v…
Extended AB Algorithms for Bistatic Integrated Sensing and Communications Systems
Tian Jiao, Yanlin Geng, Zhiqiang Wei +1
Integrated sensing and communication (ISAC) is pivotal for next-generation wireless networks, rendering the computation of rate-distortion trade-off in ISAC systems critically impo…
Channel Estimation for RIS-Aided MIMO Systems: A Partially Decoupled Atomic Norm Minimization Approach
Yonghui Chu, Zhiqiang Wei, Zai Yang +1
Channel estimation (CE) plays a key role in reconfigurable intelligent surface (RIS)-aided multiple-input multiple-output (MIMO) communication systems, while it poses a challenging…
RIS-aided MIMO Beamforming: Piece-Wise Near-field Channel Model
Weijian Chen, Zai Yang, Zhiqiang Wei +2
This paper proposes a joint active and passive beamforming design for reconfigurable intelligent surface (RIS)-aided wireless communication systems, adopting a piece-wise near-fiel…
