- Abstract
- This 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 show that the proposed scheme can
fast initialize the equalizer using less than 5000 symbols, while
providing the receiver performance comparable to that of
conventional schemes.
