A Novel Fast Recursive V-BLAST Detection Algorithm

摘要

摘要: 该文提出了一种新型的快速递归V-BLAST算法。此算法采用一种简单的矩阵伪逆递推关系，利用前一次迭代时得到的迫零加权矩阵和加权向量直接计算出下一次迭代的迫零加权矩阵和加权向量。与现有的V-BLAST检测算法相比，所提出的算法在保证最优性能的前提下，具有更低的计算复杂度和更快的处理速度。

Abstract: A novel fast recursive V-BLAST detection algorithm is proposed in this paper. Since a simple recursive relationship of computing pseudoinverses is exploited in the algorithm, the Zero-Forcing (ZF) weight matrix and the ZF weight vector at each iteration can be directly computed from the ZF weight matrix and vector determined at the previous iteration. It is shown that the proposed algorithm not only guarantees the optimal detection performance, but also has lower computational complexity and faster processing speed than the existing algorithms.
