Abstract:
A signal detection circuit includes: a correlation circuit including the first through nth correlators connected sequentially as the first through nth stage correlators and each computing a correlation value between a received signal and a spreading sequence while shifting the received signal to the next stage depending on the chip rate period of the spreading sequence; a first adder that adds k correlation values computed by k correlators so as to generate a first addition value; a second adder that adds r correlation values computed by r correlators so as to generate a second addition value; a subtractor that subtracts the first addition value from the second addition value so as to generate a subtraction value; and a synchronization detection unit that compares the subtraction value with a threshold value, so as to detect the synchronization timing of the spreading sequence and the received signal.

Claim (Index 4):
The signal detection circuit according to  claim 1 , wherein said k correlators are configured from the first through kth correlators, and said r correlators are configured from the (n\u2212r+1)th through nth correlators.
