Bayes-Optimal Joint Channel-and-Data Estimation for Massive MIMO with Low-Precision ADCs
Chao-Kai Wen, Chang-Jen Wang, Shi Jin +2
This paper considers a multiple-input multiple-output (MIMO) receiver with very low-precision analog-to-digital convertors (ADCs) with the goal of developing massive MIMO antenna s…

Performance Limits of Massive MIMO Systems Based on Bayes-Optimal Inference
Chao-Kai Wen, Yongpeng Wu, Kai-Kit Wong +2
This paper gives a replica analysis for the minimum mean square error (MSE) of a massive multiple-input multiple-output (MIMO) system by using Bayesian inference. The Bayes-optimal…

Message Passing Algorithm for Distributed Downlink Regularized Zero-forcing Beamforming with Cooperative Base Stations
Chao-Kai Wen, Jung-Chieh Chen, Kai-Kit Wong +1
Base station (BS) cooperation can turn unwanted interference to useful signal energy for enhancing system performance. In the cooperative downlink, zero-forcing beamforming (ZFBF)…
