In this paper, we propose a power-efficient configurable multiple-input-multiple-output (MIMO) detector, supporting QPSK, 16-QAM, and 64-QAM with low complexity. The approach divides a large MIMO detector into two subsystems: a core detector and a residual detector. The core detector, a low-cost 2 times 2 V-BLAST with ML detector, is used to detect the first two significant outputs. This detector not only efficiently increases the reliability of the entire MIMO detector through its ML… CONTINUE READING
