ABSTRACT:
A path timing comparing section compares correlation peak values and their path timings detected from a delay profile with correlation peak values and their path timings assigned to fingers in the previous cycle. If a path timing determining section determines from the comparison result that a path with high intensity level has appeared, it immediately assigns the path to a finger. This enables maintaining good receiving characteristics.
