... and compensates for the residual ISI after the feedforward equal- ization. We now describe how that FB filter is adapted for the direct and time-reversed TV-FD-DFEs. Direct TV-FD-DFE For the direct ... both for signal pro- cessing and for filter design. For the computation, we assume that a P-size DFT requires (P/2) log 2 (P) − P CMULs. The TV-Bi-DFE requires one DFT and two IDFTs,...
