WIRELESS RECEPTION APPARATUS AND WIRELESS RECEPTION METHOD

摘要

A wireless reception apparatus and a wireless reception method according to the present invention are capable of achieving closed loop MIMO communications in time varying channels, with a reduction in feedback information. In one embodiment of the present invention, after a first channel state information is fed back (step 475), a signal to which a transmission filter has been applied is received (step 430). The transmission filter is corresponding to the first channel state information. Using the signal, a second channel state information is generated (step 480), and then a reception filter corresponding to the second channel state information is applied to the signal (step 490).
