Transmitting digital data through dispersive channels is mainly affected by intersymbol interference (ISI). The decision feedback equalizer (DFE) was introduced as a suboptimum nonlinear processor to combat ISI for known channel characteristics. In this paper, the performance of the DFE is investigated for a mismatched channel. The channel characteristic under mismatched is allowed to vary with respect to a specified design channel characteristic for which the DFE is design. This investigation will allow us to examine the limits of mismatch for the channel performance is acceptable.
