Abstract
A hybrid equalization system includes an equalization device, a target channel impulse response device, a maximum likelihood sequence estimation device and a multiplexer. The equalization device receives a sampled baseband signal and performs an equalization operation thereon for generating first estimated symbols. The target channel impulse response device convolutes the first estimated symbol and a predetermined target channel response function for generating a training symbol corresponding to a target channel. The maximum likelihood sequence estimation device performs a maximum likelihood sequence estimation on the sampled baseband signal trained by first estimated symbols based on the target channel impulse response for generating second estimated symbols. The multiplexer selects the first estimated symbol or the second estimated symbol as an output of the hybrid equalization system according to a selection signal.
