A radio communication apparatus used in a CDMA communication system
includes a plurality of delay profile circuits for generating delay
profiles by calculating the correlations between a reception signal and
known data at a plurality of timings, and timing circuits prepared for
the respective delay profile circuits to generate correlation timings
therein. In this apparatus, the operation of at least the delay profile
circuit which generated the delay profile or the timing circuit for
generating a correlation timing in the delay profile circuit is stopped
in accordance with the correlation value of the delay profile. A power
consumption control method for the radio communication apparatus is also
disclosed.
