摘要：
An iterative modified decision feedback equaliser (I-MDFE) with no feedback filter over broadband channels is proposed. Generally, in the structure of an I-DFE, a soft residual postcursor intersymbol interference (ISI) is removed by a feedback filter (FBF). However, the ISI in the I-MDFE is precancelled prior to the equalisation, which results in no requirement of the FBF. It is demonstrated in the simulation evaluation that the I-MDFE can offer excellent performance under the broadband channel, with shorter filter taps than those of an iterative linear equaliser (I-LE) and the I-DFE.
