Abstract
A signal acquisition apparatus and method for reducing a false alarm rate are disclosed. The apparatus includes a comparator for detecting a first peak by comparing a correlation value of a received signal with a first threshold and detecting second peaks in a sample interval of the detected first peak based on a second threshold which is different from the first threshold. Thus, a signal is acquired based on a number of the detected second peaks. Accordingly, the false alarm rate due to the noise can be reduced while the detection probability is maintained even at a high SNR.
