Patent ID: 7039097

Claim:
A CDMA receiver that periodically performs a path search on A/D converted digital data after forming a delay profile by calculating correlation power at each of a plurality of delays; said CDMA receiver comprising: path search means for performing a path search on the basis of the previously calculated delay profile, splitting the delay profile measurement range into a plurality of regions, and discriminating between regions in which a path is present and regions in which a path is not present; data classifying means for classifying said A/D converted digital data into data of regions in which a path is present and data of regions in which a path is not present, on the basis of information from said path search means; a data integrator for integrating the data of the plurality of regions that have been classified by said data classifying means as regions in which a path is not present, whereby the integrated data is regarded as the data of a single imaginary region; data combining means for combining the region data that has been integrated by said data integrator, with the data of regions that have been classified by said data classifying means as regions in which a path is present; and delay profile measuring means for creating a delay profile for the data after it has been combined by said data combining means, by calculating the correlation power at each of a plurality of delays.
