Soft detector architecture based on Belief Propagation for MIMO systems

摘要: This paper presents a novel architecture of soft MIMO detector. To our knowledge, it is the first detector based on Belief Propagation algorithm. The proposed composed block that in charge calculation Euclidean distances. second one dedicated to exchange information between received nodes and candidate larger Joint Factor Graph. Thanks an appropriate level parallelism, associated enables efficient exchanges information. Therefore, promotes good trade-off error rate performance computational complexity. It also decreases latency iterative receivers.
