Apparatus for sub-carrier allocation in mimo ofdm mobile communication system and method thereof

The present invention in an orthogonal frequency division multiple access method of a mobile communication system to a plurality of subcarriers assigning to one or more users, and the said assigned sub-carriers of the plurality of one antenna of the antenna according to the use of multiple transmit antennas a method for mapping according to the method comprising the steps of: receiving channel information of subcarriers and the received channel information for each of the plurality of antennas from each of the plurality of user terminals to be assigned for each of the plurality of user terminals subcarriers with respect to the process of determining the number and the subcarriers of the number assigned to the respective user terminal, it characterized in that it comprises the step of determining a position of a subcarrier and transmitting antenna. Multi-antenna orthogonal frequency division multiple access, and sub-carrier, the minimum bit rate
