Abstract
A signal detection device rapidly and accurately detects a desired signal from a reception signal. A correlation unitoutputs a correlation value string obtained by cross-correlating an input symbol string and a reference symbol string, a first position detection unitdetects a position of a correlation value viewed as a maximum or a local maximum on the correlation value string, a compensation unitperforms compensation by suppressing correlation error values from correlation value at positions other than the detected position, a second position detection unitdetects a position of a correlation value viewed as the maximum on the compensated correlation value string, and a sync-detected signal generation unitoutputs a sync-detected signal based on the position detected by the second position detection unit
