<p>PROBLEM TO BE SOLVED: To provide a mobile radio terminal that can reduce circuit scale for path search, so as to enable stable search for paths. SOLUTION: An analog/digital converter 12 applies 4-fold oversampling to a received signal by a radio section 11 via an antenna 10, by using a sampling clock with a frequency fs and re-sampling circuits 14, 15 respectively apply re-sampling to the sampling result, by using a sampling clock having and a frequency fs/2 having a different phase generated by a clock-generating circuit 19. An adder 16 sums the re-sampling results and provides an averaged sampling result to a matched filter 17. The matched filter 17 uses the sampling clock with a frequency fs/2, to apply correlation processing to the averaged sampling result, and a peak detection section 18 detects a path from this correlation processing result.</p> |
