Abstract
An encoding method in a mobile communication system is provided. The method comprises selecting at least one adaptive coding rate and at least one modulation method according to estimated forward channel characteristics for a plurality of transmission antennas, based on BLAST-decoded signals received from a plurality of reception antennas; coding and modulating a plurality of transmission signal layers generated for transmission by the plurality of transmission antennas according to the selected adaptive coding rate and modulation method; and transmitting the plurality of transmission signal layers to the plurality of transmission antennas simultaneously by way of V-BLAST-coding.
