  • Focusing on the V-BLAST OFDM system with distributed transmit antennas in multipath fading channel, a novel signal transmission method utilizing spatial power spreading is proposed. The method takes advantage of the delays among distributed antennas and enhances frequency selectivity of the distributed channel. Thus, the achievable diversity increases. Simulation results in M.1225 pedestrian test channel show that the proposed algorithm has 2 dB gain at BER of10-3 compared to conventional method using BPSK modulation.
