Radio reception apparatus and radio reception method

Abstract

A radio reception apparatus is a radio reception apparatus for demodulating a multicarrier signal modulated according to multicarrier modulation. It includes a plurality of antenna sections, each for receiving a multicarrier signal, a plurality of carrier selection sections, each of the carrier selection sections selecting at least one subcarrier signal for each of the antenna sections out of the multicarrier signal received by each of the antenna sections, an antenna selection section for selecting a reception antenna section from among the antenna sections based on the signal strengths of the subcarrier signals selected by the carrier selection sections, and a demodulation section for demodulating the multicarrier signal received by the antenna section selected by the antenna selection section.

1 . A method for receiving radio signals with a radio receiver having a plurality of antennas, comprising: 
 receiving multicarrier signals which are modulated according to multicarrier modulation using the antennas;    selecting at least one subcarrier signal out of the multicarrier signal received by each antenna;    selecting a reception antenna among the plurality of antennas based on signal strengths of the subcarrier signals selected for each antenna;    demodulating the multicarrier signal received by the reception antenna;    measuring signal strength and distortion amounts of pilot signals in the multicarrier signal being received by the reception antenna; and    correcting the multicarrier signal received by the reception antenna using the measured signal strength and the distortion amounts.
