Abstract
To realize transmission performances equivalent to those of an MU-MIMO BLAST ZF-THP system without increasing a signal processing amount in a base station apparatus in a downlink MU-MIMO transmission system. A transmission apparatus is provided with a plurality of transmission antennas, generates a transmission signal addressed to each reception apparatus based on information indicating spatial correlation of channels to and from a plurality of reception apparatuses, space-multiplexes the generated each transmission signal in the same wireless resource, and transmits it to each reception apparatus. The transmission apparatus includes: an ordering determination partwhich determines an order in which a transmission signal addressed to each reception apparatus is generated based on information indicating spatial correlation of channels; a linear filter generation partwhich generates a linear filter based on the determined order; a THP partwhich performs a THP process by using the determined order and the linear filter; and a linear filter multiplication partwhich multiplies an output of the THP partby the linear filter.
