摘要：
A CDMA mobile communication demodulator circuit has a path timing comparison part 4 operable to compare a difference between path timings of adjacent paths with a predetermined threshold value, a path level comparison part 5 operable to compare power correlation values of the path timings of the paths determined to be controlled with a maximum power correlation value between those path timings, and a path timing determination part 3 operable to control the finger assignment timings based on the comparison results. By adaptively controlling finger assignment timings in accordance with a power correlation peak value obtained by a delay profile calculation, good receiving characteristics can be maintained, and electric power consumption can be reduced.
