Sphere decoding (Sphere Decoder, SD) algorithm can achieve lower complexity MIMO (Multiple Input Multiple Output, MIMO) system, optimal detection, are currently subject to widespread concern MIMO detection algorithm. The main findings of the current sphere decoding were reviewed, classified according to the search strategy, the depth of focus of the analysis based on the priority strategies VB, CL and K-Best, FSD algorithm based on breadth-first strategy, and discuss the selection of the initial radius of several methods Finally, in the quasi-static flat Rayleigh fading environment on the performance of these algorithms are simulated and compared
