Chung-An Shen, et al., "Evaluation framework for K-best sphere decoders." Journal of Circuits, Systems, and Computers 19 (05), 2010, 975. While Maximum-Likelihood (ML) is the optimum decoding scheme for most communication scenarios, practical implementation difficulties limit its use, especially for Multiple Input Multiple Output (MIMO) systems with a large number of transmit or receive antennas. Tree-searching type decoder structures such as Sphere decoder and K-best decoder present an interesting trade-off between complexity and performance. Many algorithmic developments and VLSI
