An adaptive equalization apparatus within a receiver comprises a timing detector (101) that detects a timing suitable for an adaptive equalization processing, by using a first unique word, a timing adjuster (100) that extracts a standardized received signal based on a detection timing, a CIR initial value estimator (103) that estimates an initial value of a channel impulse response by using a first unique word, a CIR initial value setter (104) that sets a plurality of channel impulse response initial values based on estimated initial value, and an adaptive equalizer (102) that individually judges presence or absence of a timing slip when each initial value is used, by judging a distance between a first unique word and a second unique word disposed at a back side, and obtains a decision value by using a channel impulse response initial value that does not generate a timing slip and the extracted received signal. <IMAGE> |
