PROBLEM TO BE SOLVED: To provide a CDMA receiver capable of substantially shortening the processing amount of the arithmetic operation of a path search part, reducing current consumption, simplifying hardware constitution and improving follow-up ability to the fluctuation in a path. SOLUTION: The average power calculation part 11 of a DSP 1 calculates the average power of a delay profile and a valid data judgement threshold calculation part 12 calculates a valid data judgement threshold for judging whether or not the correlation data of the delay profile are the data of a valid path based on the average power. A valid data judgement part 13 judges the valid data of the delay profile based on the valid data judgement threshold, selects only valid correlation data and preserves them in a valid correlation data table preservation part 15. A correlation peak position detection part 17 detects the positions of plural correlation peaks and preserves them in a detected path table preservation part 16. A Rake path allocation part 18 decides path allocation to a Rake reception part 7. |
