the two LDPC decoding algorisms on MIMO with analogue network coding (ANC) in two-way amplify-and-forward (AF) relaying where multi-antenna nodes communicate via a single antenna relay are proposed. To be more specific, the simulation of the comparative analysis of un-coded and coded information in two-way relaying with non-identical Nagakgami-m fading between the hops is presented. To facilitate the comparison, we analysis the sum symbol error rate (SSER) of each MIMO case under Nakagami-m fading. And a pivotal conclusion is reached that as m and N increased, the SSER of the information is progressively reduced and Log Likelihood Ratio Belief Propagation (LLR BP) Based algorism is a little better than Modified (Uniformly Most Powerful Belief Propagation) UMP BP Based algorism within less than 1 dB in this model case.
