Abstract:
1. A scalable Multiple-Input Multiple-Output (MIMO) detector, comprising: an ordering block determining an order of the columns of a channel matrix including received streams based on the power of each column of the channel matrix; a group interference suppression block coupled to the ordering block for grouping the received streams into a core part and a residual part, the core part including a first received stream and a second received stream corresponding to the first two columns of the channel matrix in the order, the first received stream and the second received stream forming a received signal vector, and the residual part including the rest of the received streams; a core detector coupled to the group interference suppression block for detecting the core part based on a 2×2 Maximum Likelihood (ML) detection; and a residual detector detecting the residual part by Vertical Bell Laboratories Layered Space Time (VBLAST) detection.
