A diversity control technique for use in a diversity receiver having an antenna selection diversity mode and a diversity combining mode is disclosed. A signal strength detector detects a received signal strength from a received signal. A fading pitch detector detects a fading pitch from the received signal strength. A quality detector detects a received signal quality based on the received signal. One of the antenna selection diversity mode and the diversity combining mode is selected depending on whether at least one of the received signal strength, the fading pitch, and the received signal quality has been deteriorated. In the case of the antenna selection diversity mode, a radio receiving system other than a normally used radio receiving system is powered off. |
