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.
