Patent ID: 7474692

Claim:
A radio reception system capable of receiving signals from a plurality of transmitters using a plurality of antennas, comprising: a signal processing unit performing a prescribed signal processing on the signals received by said plurality of antennas; a plurality of first signal extracting units extracting signal components corresponding to said plurality of transmitters, respectively, based on a signal output from said signal processing unit; a plurality of first estimating units estimating parameter information related to relation between the signal components extracted by said first signal extracting units and the received signal output from said signal processing units; a plurality of first error determining units determining whether the signal components corresponding to the plurality of transmitters extracted by said first signal extracting units include a demodulation error or not, respectively; and a first operating unit subtracting, from the signal output from said signal processing unit, said extracted signal component determined by said first error determining unit not to include any demodulation error, in consideration of corresponding said parameter information.
