A correlation detection device capable of detecting the prescribed code sequence from input signal with a simple construction. Since the input signal (S40), after the amplitude of this signal is regulated to the fixed value, is entered into the matched filter means (71), an accidental output by the matched filter means of the correlation value having large signal level can be prevented, and only code sequence to be detected can be correctly detected, and thereby the correlation detection device capable of detecting the prescribed code sequence from input signal correctly and with a simple construction can be realized. <IMAGE> |
