Doppler Diversity Transmitter for OFDM Wireless Mobile Communications Based on Fixed Track

Abstract:

A Doppler diversity transmitter for OFDM high-speed mobile communications based on fixed track is proposed. Because of fixed track, we can get the channel information and branches’ weights in advance, utilize the channel information do pre-equalization for every branch in transmitter. After modulation, branch outputs are individually frequency shifted, weighted and added together. Extensive simulations show that the proposed transmitter alters the statistics of the fading to improve BER significantly and better than the Doppler diversity receiver’s performance.
