ABSTRACT:
A correlator 1 and an amplitude detection section 2 detect a correlation value of a spectrum spread signal. A maximum value detection section 5 detects a maximum correlation value for each symbol, which is then sequentially added by an adder section 6. A carrier detection section 4 compares the added value with a threshold value so as to detect presence/absence of carrier.
