Abstract:
1. A communication apparatus comprising: a matched filter unit that generates a correlation value between a received signal and a predetermined reference signal; an evaluating unit that generates a timing signal based on a correlation value of a first received signal transmitted in a first frequency band, the timing signal indicating a symbol timing of the first received signal; a detection window generating unit that generates a maximum value detection window based on the timing signal, the maximum value detection window, opened for a predetermined time period, for, detecting a peak of the correlation value of a second received signal transmitted in a second frequency band; a maximum value detecting unit that detects the peak of the correlation value of the second received signal in the maximum value detection window; and a correction unit that corrects a deviation in a frequency or a phase in the second frequency band based on the peak of the correlation value detected by the maximum value detecting unit.
