Abstract
A wireless transmission apparatus able to reliably increase outage capacity according to the state of a propagation path. This apparatus is a wireless transmission apparatus () which transmits a plurality of streams to a wireless reception apparatus; wherein a time/space allocation determining unit () determines the spatial multiplex stream number based on the desired multipath number and the number of reception antenna ports of the wireless reception apparatus, said desired multipath number being calculated based on the detected multipath number, the number of reception antenna ports, and the desired error rate for the plurality of streams; a stream dividing unit () divides the transmission data into a plurality of streams of that spatial multiplex stream number; a transmission weight calculation unit () calculates a transmission weight based on the desired multipath number, spatial multiplex stream number, and a channel estimation value; and a time precoding unit () and a spatial precoding unit () use the transmission weight to precode the plurality of streams.
