摘要：
The present invention switches an interference suppression system between a linear precoding and a nonlinear precoding in accordance with a communication environment. A wireless transmission apparatus is provided with a plurality of transmission antenna units (303), and multiplexes spatially and transmits a plurality of series of data with respect to at least one wireless reception apparatus, and includes a selection unit (307) configured to select any one precoding system from a plurality of types of precoding systems and a precoding unit (315) configured to carry out precoding with respect to the plurality of series of data using the selected precoding system. In addition, the selection unit selects either of a first precoding system carrying out linear processing with respect to the plurality of series of data or a second precoding system carrying out nonlinear processing with respect to the plurality of series of data.
