Abstract
The present invention provides a diversity receiver and diversity reception method utilized for CDMA communication system. Antenna switching using antenna diversity is made possible with one decoding subsystem without losing the received data. A receive subsystemreceives an intermittent signal for standby operation by a first antennaor a second antenna, the signal being sent out every slot cycle from each base station. Information about the received field strengths at the first and second antennas,and, is acquired from the signal received by the receive subsystem. Base on this information, one of the first antennaand second antennain a better reception environment when a transition is made from standby mode to a phone conversation is switched and connected to the receive subsystem. Then, the conversation is performed.
