Convergence of Gaussian belief propagation over a ring-type graphical model
Seokhyun Yoon · 2012
We consider the joint MIMO detection algorithm based on ring-type Pair-wise Markov random fields (MRF) in [1] for Gaussian input to obtain the Gaussian BP that is run over the ring-type MRF and proves its convergence in mean to the linear MMSE estimates. The result lies on the same line of those in [2] and [3], but with differences in its graphical model and the message passing rule.
