<p>PROBLEM TO BE SOLVED: To reduce a demodulation error caused by updating a reception sampling point in a receiver adopting a pilot interpolation synchronous detection system. SOLUTION: In the insertion synchronous detection method in the radio communication system where a receiver side can detect an interpolated synchronizing signal by periodically inserting a pilot symbol whose phase point is known to an information signal, the synchronous detection of the information signal set between the pilot symbols is conducted through linear interpolation of a transfer function estimated from the pilot symbols before and after the information signal, and a reception sample point timing used for the synchronous detection is updated at a midpoint of the pilot symbols before and after the information signal.</p> |
