中文摘要	A feedback frequency domain equalization method based on an approximate parallel receiver (APRX) structure was developed to improve data throughput for wideband wireless communications. The method uses pseudo-random number sequence correlation to get the channel estimate, and then feeds the estimated channel coefficients back to update the frequency-domain equalizer coefficients. The structure not only improves high-speed transmissions, but also effectively suppresses frequency selective fading. Simulations show that APRX can not work in multipath channel environments, while that the urment feedback frequency domain equalization method works well with only 4 dB performance degradation with an additive white Gaussian noise channel.
