Patent ID: 7596168

Claim:
A diversity receiving apparatus to which first and second reception signals received by different antennas are input, comprising: one or more phase shifters that generate one or more third signals having phases different from the second reception signal based on the second reception signal; a correlation calculator that obtains a correlation between the first reception signal and each of the second reception signal and the third reception signals; a correlation comparator that selects the reception signal having the highest correlation with the first reception signal from the second reception signal and the third reception signals; a selector that selects and outputs one of the second reception signal or the third reception signals, based on an output of the correlation comparator; a combining device that outputs a signal formed by combining the first reception signal and the reception signal output from the selector; and a trigger issuing section that issues a trigger signal at predetermined time intervals, wherein the correlation calculator obtains the correlation between the first reception signal and each of the second reception signal and the third reception signals every time the trigger signal is issued, and wherein the correlation comparator selects the reception signal having the highest correlation with the first reception signal from the second reception signal and the third reception signals every time the trigger signal is issued.
