A Improved QRD-M Algorithm for MIMO Signal Detection
MIMO通信系统中QRD-M检测算法的改进

Based on a proposed equivalent model of two concatenated modules, the conventional QRD-M algorithm for MIMO signal detection was studied and an improved QRD-M algorithm was proposed in this paper. Through complexity analysis and numerical simulations, it is proved that the proposed algorithm can provide a more flexible tradeoff between system performance and the complexity of MIMO detection.
