<P>PROBLEM TO BE SOLVED: To provide a radio base station device transmitting a Pre-Rake synthesized signal with a low communication error rate under an environment where a radio propagation path has a time variation. <P>SOLUTION: In a base station, a phase rotation amount is estimated which is at the time of being about to transmit data from each path of a delay profile in the past to compensate a phase of the delay profile based on the estimated value. As a result, a Pre-Rake synthesized signal following a time variation of a radio propagation path can be generated, thereby reducing a communication error rate. <P>COPYRIGHT: (C)2012,JPO&INPIT |
