该文对MIMO通信系统中的QRD—M检测算法进行了研究,将其分解为两个级联检测的等效模型,并据此提出了对传统QRD—M检测算法的改进方案,进行了复杂度分析。性能仿真证明该改进算法能够更灵活地实现系统性能和复杂度的折衷设计,可以在相同或相近复杂度的条件下获得更好的性能。
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.
