Transmitter/receiver for controlling multiuser multiple input multiple output system and method thereof

A control method of a MIMO system, a transmitter/receiver used for the same and a control method thereof are provided to prevent the limitation of existing PU2RC, PARC, and PSRC and reduce feedback load for improving performance. A receiver(250) controls a multiuser multiple antenna transceiving system. A channel estimator(255) estimates a channel about a plurality of transmission-reception antennas. A feedback unit(256) transmits the generated feedback information to a transmitter and determines feedback information production based on the presumed channel. A decompression module(251) restores a plurality of data streams.
