Abstract:Adaptive LMS-DFE is preferred as an effective solution to coping with inter-symbol interference (ISI) for ATSC DTV receivers. In the DTV channel, echo delay often covers hundreds of symbols, by performance constrains, which leads to very large-scale equalizer with huge computational complexity. One consequence of the adaptive large-scale equalizer is that of very slow convergence. It is combined with error propagation, the inherent drawback of DFE, seriously deteriorating the performance of the receivers, espe… Show more
