Abstract

A multiple antenna communication method and a multiple antenna communication system are provided. The multiple antenna communication method includes: determining a weighting vector with respect to a plurality of transmit antennas, using a spread spectrum code; determining a target transmission rate of each of the transmit antennas using the determined weighting vector; transmitting information associated with the target transmission rate to a multiple antenna reception apparatus; receiving, from the multiple antenna reception apparatus, channel information including information regarding whether to accept the transmitted target transmission rate information; and transmitting data to the multiple antenna reception apparatus using the received channel information.
