摘　　要：针对V-BLAST的检测问题,文中基于MMSE准则,提出了一种新的高效解码算法。相对原始V—BLAST检测算法,文中所提算法不仅计算复杂度明显降低,而且检测性能也有较大改善。仿真实验给出了文中算法与其它解码算法的性能对比,证明了文中算法的良好性能。In this paper,a new and efficient decoding algorithm for V-BLAST,which is based on MMSE criterion,is presented.Compared with original V-BLAST detection algorithm,the computational complexity of the proposed algo- rithm is reduced obviously,and its detection performance is also improved.In the simulations,the proposed algorithm is compared with other decoding algorithm,and its efficiency is also showed.
