Patent ID: 7876809

Claim:
A Code Division Multiple Access (CDMA) receiving apparatus comprising: delay profile generating means for generating, for one radio link, delay profiles from both a common pilot channel on which no transmission power control is performed and an individual channel on which transmission power control is performed; and path search means for searching for effective paths on the basis of the delay profiles generated by said delay profile generating means; wherein said delay profile generating means comprises: a spreading code generator which generates a spreading code for the common pilot channel and a spreading code for the individual channel; and a delay profile unit which generates a delay profile concerning the common pilot channel and a delay profile concerning the individual channel by accumulating correlation values between a reception signal, the spreading code for the common pilot channel, and the spreading code for the individual channel; and wherein said path search means comprises: means for detecting path timings from both the delay profile concerning the common pilot channel and the delay profile concerning the individual channel which are generated by said delay profile generating means, and searching for effective paths in descending order of reception power.
