It is discussed in the paper that based on the mathematic process the nonlinear DFE equalizer could be linearlized and discomposed into 2 symmetric linear equalizers,which could be placed at the source part and the receiver part of the serious multipath interference transmission channel(such as high speed transmission in tunnel where serious multipath interference exists).Compared with the classical nonlinear DFE equalizer,the system complexity of the new one has been reduced while it still keeps the high performance of DFE.Moreover,those symmetric structures could result in easier realization of dual direction transmission.Finally,the algorithm has been proved to be effective based on software simulation.
