A novel approach to analyzing the performance of the V-BLAST multi-input multi-output systems with two transmit antennas is presented in this letter. Based on the properties of Wishart matrices, we derive the exact SNR distributions in the first and second detection steps when optimal detection ordering is used. Closed-form analytical expressions for the bit error rates are then given. The effect of optimal ordering on the diversity order and SNR is evaluated. The results are found to be consistent with those previously published by other researchers
