<p>PROBLEM TO BE SOLVED: To provide a small circuit scale for use with many fingers and to also improve sample selection accuracy. SOLUTION: A maximum detecting circuit 15 detects samples which become maximum from among the correlation peak detection output received from a matched filter 14, and a best-16 detection circuit 16 selects higher rank samples which are higher than the number of fingers out of the maximum samples. Thereby the data which are ultimately unnecessary despite their large value can be previously eliminated and as the samples to remain, only the number of samples is necessary by the number of paths for a synthesis ratio calculation part 17 to calculate a synthesis ratio. As a result, the circuit scale can be reduced significantly.</p> |
