Abstract:
1. A wireless transmission apparatus which includes a plurality of transmission antennas, and with respect to a plurality of wireless reception apparatuses, multiplexes spatially and transmits a plurality of series of data, comprising: a selector configured and/or programmed to select either of a first precoding method carrying out linear processing with respect to said plurality of series of data or a second precoding method carrying out nonlinear processing with respect to said plurality of series of data based on channel information acquired from said plurality of wireless reception apparatuses or information derived from said channel information; and a precoder configured and/or programmed to carry out precoding with respect to said plurality of series of data using said selected precoding method; wherein said selector configured and/or programmed to select said first precoding method in a case where a spatial correlation value of each channel between said wireless transmission apparatus and said plurality of wireless reception apparatuses is smaller than a predetermined threshold value, and to select said second precoding method in a case where said spatial correlation value is larger than said threshold value.
