The fast-growing wireless communication field demands high transmission capacity and quality. In order to achieve the above requirements, the best approach for real time application would be combining Multi-Input Multi-Output (MIMO) and Orthogonal Frequency Division Multiplexing (OFDM). Vertical Bell-Labs Layered Space Time (V-BLAST) is a symbol-detection algorithm. The combination of V-BLAST with other available detection schemes improves system performance significantly. In this paper, the possible combinations of detection schemes along with V-BLAST is compared based on their Minimum Bit Error Rates (MBER) to their corresponding Signal to Noise Ratio (SNR) values and the best promising combination is proposed. Also the transmit power of antennas is allocated for the best combination using the Lagrangian procedure and is compared with the conventional power allocation scheme. © 2011 IEEE.
