Abstract:
1. A transmission apparatus which is provided with a plurality of transmission antennas and a computer, and transmits a wireless signal to a plurality of reception apparatuses, wherein based on information indicating spatial correlation of channels between the transmission apparatus and said plurality of reception apparatuses, a transmission signal addressed to said each reception apparatus is generated, and said generated each transmission signal is space-multiplexed in the same wireless resource, and transmitted to said each reception apparatus; said transmission apparatus comprising: an ordering determination part performed by the computer to determine an order in which a transmission signal addressed to said each reception apparatus is generated based on said information indicating spatial correlation of channels; a THP part performed by the computer to carry out THP (Tomlinson Harashima Precoding) processing by using said determined order and said linear filter; and a linear filter multiplication part performed by the computer to multiply an output of said THP part by said linear filter, wherein said transmission apparatus generates successively from a transmission signal addressed to a reception apparatus said information indicating spatial correlation of channels of which is large, a transmission signal addressed to said each reception apparatus.
