Abstract：An efficient Sphere Decoding (SD) algorithm is proposed for uncoded Multi-Input Multi-Output (MIMO) systems with a large number of antennas and higher modulation constellations. This method utilizes a channel-based group detection strategy. The transmitted symbols on each substream are detected by performing sphere decoding within each group and successive interference canceling between groups. Analyses and simulations demonstrate that the proposed algorithm can approach Maximum Likelihood (ML) detection with a relatively low complexity.
