ABSTRACT:
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.
