A wireless communication system includes a channel estimation circuit, a shortening circuit, a time-domain decision feedback equalizer and a coefficient calculation circuit. The channel estimation circuit generates an estimated channel pulse response according to a received signal. The shortening circuit defines a shortened impulse response from the estimated channel impulse response according to a main energy distribution region of the estimated channel impulse response. The time-domain decision feedback equalizer performs time-domain equalization on the received signal, and includes a feedforward filter for filtering the received signal. The coefficient calculation circuit calculates, according to the shortened impulse response, a set of feed-forward filter coefficients to be utilized by the feedforward filter.
A wireless communication system, comprising:
The wireless communication system according to claim 1, wherein the coefficient calculation circuit is adaptively configured instead of performing calculation according to the shortened impulse response having a predetermined channel length;
The wireless communication system according to claim 1, wherein the time-domain feedback equalizer comprises a feedback filter, and the coefficient calculation circuit calculates, according to the estimated channel impulse response, a set of feedback filter coefficients for the feedback filter.
The wireless communication system according to claim 1, wherein the time-domain decision feedback equalizer comprises a feedback filter, and the coefficient calculation circuit further calculates, according to the shortened impulse response, a set of feedback filter coefficients for the feedback filter.
