PROBLEM TO BE SOLVED: To carry out control for reception antenna diversity without quality deterioration of a received signal. SOLUTION: A PE bit is detected from packet data received by the first reception slot of each frame. In this PE bit period, a main antenna 1 and a sub antenna 24 are alternately switched to measure respective RSSIs. Based on the result of measurement, an antenna on the side of higher RSSI is selected and connected to an antenna duplexer 2. COPYRIGHT: (C)2007,JPO&INPIT
