ABSTRACT:
A post-cursor tap coefficient of a decision feedback equalizer is used as a coefficient of an echo canceler during a cold-start echo canceler training period in which a communication start-up training is carried out in an initial state and during a cold-start received signal detection period, so that an echo cancellation characteristic can be improved without increasing the circuit scale of the echo canceler and a high-speed, error-free received signal detection can be attained.
