<p>PROBLEM TO BE SOLVED: To sufficiently reduce bit errors even if a detection signal obtained by detecting a high frequency signal induced at an antenna deteriorates in quality by applying an information processor, an IC card, and a reader writer to, for example, a noncontact IC card system. SOLUTION: Detection results S2 and S3 are sampled at a high speed, data D2 and D3 are decoded with a distribution of signal levels of the detection signals S2 and S3, and the data are decoded by detecting a correlation value indicating the identity between a clock and a detection signal.</p> |
