In the literature, the decision feedback equalization (DFE) with a hybrid structure (H-DFE) [8,9], where the feedforward (FF) filter is realized in the frequency domain (FD) while the feedback (FB) filter is realized in the time domain (TD), is derived to cancel the ISI with the disadvantages of relatively high design complexity and error-propagation phenomena.
