Abstract :
A novel time-frequency processing scheme is developed to exploit Doppler diversity of time varying multipath channel for OFDM mobile communication systems. Extensive simulations show that the proposed time-frequency MMSE processing scheme alters the statistics of the fading to improve BER significantly.
