Chung-An Shen, et al., "A Best-First Soft/Hard Decision Tree Searching MIMO Decoder for a 4×4 64-QAM System" IEEE Transactions on Very Large Scale Integration (VLSI) Systems 20, (8), 2012, 1537. Abstract: This paper presents the algorithm and VLSI architecture of a configurable tree-searching approach that combines the features of classical depth-first and breadth-first methods. Based on this approach, techniques to reduce complexity while providing both hard and soft outputs decoding are presented. Furthermore, a single programmable parameter allows the user to tradeoff throughput versus BER
