Low-Complexity Message Passing Based Massive MIMO Channel Estimation by Exploiting Unknown Sparse Common Support with Dirichlet Process
Zhengdao Yuan, Chuanzong Zhang, Zhongyong Wang +1
This paper investigates the problem of estimating sparse channels in massive MIMO systems. Most wireless channels are sparse with large delay spread, while some channels can be obs…

A New Combination of Message Passing Techniques for Receiver Design in MIMO-OFDM Systems
Chuanzong Zhang, Zhengdao Yuan, Zhongyong Wang +1
In this paper, we propose a new combined message passing algorithm which allows belief propagation (BP) and mean filed (MF) applied on a same factor node, so that MF can be applied…
