Abstract:
1. A reception apparatus comprising: a plurality of reception antennas configured to receive transmission signals transmitted from a plurality of transmission antennas; a first interference processing section configured to perform a weighting processing of imparting a weight to reduce a multipath interference component corresponding to an intersymbol interference based on a multipath adjusting an amplitude of an inter-antenna interference component that a transmission signal from one transmission antenna gives to a transmission signal from another transmission antenna; and a second interference processing section configured to remove the inter-antenna interference component with respect to each of the plurality of reception signals on which the weighting processing is performed, wherein the first interference processing section includes a weight calculation section configured to calculate a weight factor at which only the power of the multipath interference minimized on the basis of a propagation channel vector estimated on the basis of the reception signal and a correlation matrix between a plurality of transmission and reception antennas, an equalizer configured to perform a weighting processing on the reception signal with the calculated weight factor, and a correction section configured to add the inter-antenna interference component to the reception signal after the weighting processing.
