Abstract:
1. A receiving apparatus comprising: a receiving section that receives a reception signal and outputs a reception quadrature baseband signal based on the reception signal; an amplitude distortion estimator that outputs an amplitude estimation signal estimating an amplitude distortion of the reception quadrature baseband signal, using a pilot symbol included in the reception quadrature baseband signal; and a frequency distortion estimator that outputs a frequency estimation signal estimating a frequency distortion of the reception quadrature baseband signal, using the pilot symbol included in the reception quadrature baseband signal, wherein the reception quadrature baseband signal is a signal in which a second symbol placed immediately before the pilot symbol, the pilot symbol, the second symbol placed immediately after the pilot symbol and a first symbol as a data symbol are placed in order; a signal point of the pilot symbol is a symbol placed on an I axis or a Q axis on an IQ plane; and the second symbols are each placed in one signal point among a plurality of signal point candidates placed on the same axis which being placed the signal point of the pilot symbol.
