Receiver and synchronous acquisition method |
摘要 |
A correlation calculating section 103 calculates correlation values from a baseband signal from a radio receiving section 102. A delay profile generating section 105 generates a delay profile based on the correlation value from a selecting section 104. A peak detecting section 106 detects a peak correlation value and a peak phase from the delay profile, outputs the peak correlation value to a weighting section 109, and also outputs the peak phase to a correlation phase adjusting section 107 and a demodulation control section 111. A correlation phase adjusting section 107 adjusts a phase of a spreading code auto-correlation value in accordance with the peak phase, and the weighting section 109 adjusts amplitude of the spreading code auto-correlation value subjected to phase adjustment in accordance with the peak correlation value. A correlation eliminating section 110 eliminates the spreading code auto-correlation values subjected to phase adjustment from the correlation values. <IMAGE> |
