Abstract

The present invention relates to a transmitting/receiving apparatus and method in a multiuser MIMO (Multiple Input Multiple Output) system. According to the present invention, considering that each receiver having a multiplicity of antennas uses an antenna synthesis method or a receiving antenna selection method to receive a stream from a transmitter, channel information therefor is fed back such that channel information to feed back to the transmitter can be reduced and system performances can be improved.
