摘要

PROBLEM TO BE SOLVED: To reliably correct phase rotation and amplitude change in each subcarrier in multicarrier communication. SOLUTION: Interpolation pilot carriers for interpolating a plurality of pilot carriers is arranged between the plurality of pilot carriers, and data are transmitted through the interpolation pilot carriers and data carriers. A receiving side respectively detects phase rotation quantity and amplitude change quantity about the pilot carriers and the interpolation pilot carriers, and calculates a phase correction value and an amplitude correction value for the interpolation pilot carriers and the data carriers by interpolating the phase rotation quantity and the amplitude change quantity. Appropriate phase and amplitude correction corresponding to a transmission path characteristic change in each subcarrier can be performed by using the correction values to correct the phases and amplitude of the interpolation pilot carriers and the data carriers.
