Abstract

See full text

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 part 601 which 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 part 603 which generates a linear filter based on the determined order; a THP part 605 which performs a THP process by using the determined order and the linear filter; and a linear filter multiplication part 607 which multiplies an output of the THP part 605 by the linear filter.
