IEEE Transactions on Wireless Communications.1536-1276http://nrs.harvard.edu/urn-3:HUL.InstRepos:2748552In multiple-input multiple-output systems, an ordered successive interference canceller, termed the vertical Bell laboratories space-time (V-BLAST) algorithm, offers good performance. This letter presents a low-complexity V-BLAST scheme suited for parallel implementation. The proposed scheme, using a greedy ordering, can achieve a performance comparable to that of V-BLAST with optimum ordering, while its computational complexity is lower than a linear detector.en-USMIMOV-BLASTgreedy ordering10.1109/TWC.2009.070498
