N2 - In an attempt to improve the spectral efficiency of wireless communication systems, MIMO spatial multiplexing architectures have been introduced. The V-BLAST is proposed as an efficient receiver structure in terms of performance and computational complexity. In this paper, we introduce a transmit antenna selection schemes for V-BLAST type receiver with an assumption that channel information is available in the transmit side. With a given MIMO channel matrix, we derive a simplified channel capacity and vector symbol error probability in V-BLAST. Using these results, this paper provides the optimal criteria of transmit antenna selection in term of capacity and error probability. These criteria are based on tap weight vectors in V-BLAST detection. Additionally, we propose sub-optimal methods that achieve near-optimal performance with low computational load. To verify the efficiency of proposed schemes, computer simulation results are presented.
