This paper presents the symbol error rate (SER) performance of a capacity-aware adaptive MIMO beamforming scheme, which seeks iteratively, the beamforming weight vectors that enhance the capacity of OFDM-SDMA systems. We derive closed-form expressions for the SER performance of OFDM-SDMA systems, with MIMO-MRC and the proposed capacity-aware MIMO beamforming scheme. It is shown that the capacity-aware MIMO beamforming scheme enhances the SER performance of OFDM-SDMA systems, and outperforms conventional beamforming schemes such as the MIMO-MRC system.
