Abstract For Multiple-Input Multiple-Output (MIMO) space-time coding architecture with distributed transmit antennas, the location of transmit antennas will impact the system performance. To solve this problem, the area averaged bit error ratio (AABER) of V-BLAST with two distributed transmit antennas in a linear cell is studied, considering the effects of channel propagation delay, path loss, shadow fading, multipath fading and white Gaussian noise. Theoretical analyses show that the antennas should be located symmetrically about the cell center in order to achieve the best AABER. This location can be calculated by numerical method. Simulation results prove the correctness of the theoretical analysis.
