A spreading code determining section ( 107 ) determines which spreading code is multiplexed in a received signal that has been received by an antenna ( 101 ) and has gone through a radio receiver ( 102 ), a correlation processing section ( 103 ), a delay profile generator ( 104 ), a midamble shift determining section ( 105 ), and a path selector ( 106 ). When determining that it is during DTX, from the output of the spreading code determining section ( 107 ), a DTX determining section ( 110 ) reports this to the radio receiver ( 102 ), the path selector ( 106 ), a JD operation section ( 108 ), and a despreading/RAKE-combination section ( 109 ) to make them stop processing. Thus, despreading, RAKE combination, and JD demodulation of the received signal are suspended during DTX, so that power consumption can be suppressed.
