Abstract

An adaptive modulation apparatus and method using a multiple antenna selection scheme are provided. The adaptive modulation method using the multiple antenna scheme includes: selecting one transmit antenna from a plurality of transmit antennas; determining a target transmission rate of the selected transmit antenna to transmit the determined target transmission rate to a multiple antenna reception apparatus; receiving, from the multiple antenna reception apparatus, feedback information including information regarding whether to accept the target transmission rate; and transmitting data to the multiple antenna reception apparatus using the received feedback information.
