Patent ID: 7333792

Claim:
A receiving apparatus comprising: a receiving unit receiving a plurality of signals using respective carriers; a converting unit converting an in-phase component value and a quadrature component value of each of said received plurality of signals into a phase component value; a first phase rotating unit generating a plurality of reference phase values corresponding to said phase component values produced by conversion by said converting unit, based on said phase component values, and rotating said phase component values in accordance with said plurality of reference phase values thus generated; a second phase rotating unit estimating an error in each of said phase component values rotated by said first phase rotating unit with respect to a phase component value of a pilot signal contained in at least selected one of said phase component values rotated by said first phase rotating unit, based on the phase component value of the pilot signal, and rotating, for a second time, each of said phase component values rotated by said first phase rotating unit, based on the estimated error; and a retrieving unit retrieving data from each of said phase component values rotated by said second phase rotating unit for a second time.
