摘要

针对OFDM移动通信系统时变多径信道的多普勒分集问题，提出了一种新的时频处理方案。大量仿真结果表明，提出的时频MMSE处理方案改变了衰落统计量，显著提高了误码率。

Doppler diversity for OFDM wireless mobile communications. Part II: time-frequency processing

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.
