在无线通信中，存在着严重的多径现象，能够引起严重的ISI。判决反馈均衡器（DFE）是目前最常用的一种消除ISI的均衡器。本程序使用Matlab实现的QPSK下的DFE。(In wireless communication, there is a serious multi-path phenomenon, can cause severe ISI. Decision feedback equalizer (DFE) is the most commonly used in an equalizer to eliminate the ISI. This procedure using Matlab under QPSK realize the DFE.)
