Abstract An improved algorithm based on the bi-directional M-BCJR algorithm for V-BLAST in the frequency selective channel is proposed in this paper. The improved algorithm improves the performance of the bi-directional M-BCJR algorithm with little complexity increase by using a new metric and using the Kullback-Leibler distance for bi-directional search. The performance of the improved algorithm is confirmed by simulations.
