Abstract

Multipath distortion in a digital mobile channel can be alleviated by using the orthogonal frequency division multiplexing system in which the discrete Fourier transform is used for multiplexing N subchannels. Albeit every subchannel is subject to a flat fading, the difference in fading level results in intersymbol interference. Five equalization methods are studied, and their performance is compared. It is concluded that the minimum-mean-squared-error block linear equalizer is a good compromise between complexity and performance.
