dc.description.abstractThis paper proposes a fast initialization technique for equalization of 8-VSB-based digital television (DTV) signal in severe
multipath channels. We consider the use of a modified decision feedback equalizer (MDFE) [1], [2] for fast initialization. The feedback filter (FBF) of the MDFE can be initialized simply by estimating the channel impulse response and only the feedforward
filter (FFF) of the MDFE need training for initialization. To overcome the shortage of the training sequence in the VSB DTV signal,
we propose a new initialization method by generating a virtual training signal to initialize the FFF of the MDFE. Simulation results showthat the proposed scheme can fast initialize the equalizer using less than 5000 symbols, while providing the receiver performance comparable to that of conventional schemes.
