Abstract
A correlation calculating section calculates correlation values from a baseband signal from a radio receiving section . A delay profile generating section generates a delay profile based on the correlation value from a selecting section . A peak detecting section detects a peak correlation value and a peak phase from the delay profile, outputs the peak correlation value to a weighting section , and also outputs the peak phase to a correlation phase adjusting section and a demodulation control section . A correlation phase adjusting section adjusts a phase of a spreading code auto-correlation value in accordance with the peak phase, and the weighting section adjusts amplitude of the spreading code auto-correlation value subjected to phase adjustment in accordance with the peak correlation value. A correlation eliminating section eliminates the spreading code auto-correlation values subjected to phase adjustment from the correlation values.
