System and method for allocating adaptive modulation and coding sub-channel in communication system

The present invention is an adaptive modulation / coding in a communication system for transmitting and receiving data via at least one or more antennas: relates to (AMC Adaptive Modulation and Coding) sub-channel assignment system and method. For this purpose the receiving apparatus in the present invention, including to select the optimum frequency band for inspecting the channel received from the transmitting apparatus, and selecting an antenna transmission method corresponding to the result, and corresponds to the selected system, the selection information transmitting feedback information to the transmitter, and the transmission apparatus allocates the frequency ranks to the receiver receives the feedback information to the transmission, corresponding to the received feedback information. Adaptive Modulation and Coding (AMC), AMC Band Allocation, OFDMA, multiple antenna (MIMO, MISO, SIMO), Channel Quality Indicator (CQI), Channel Capacity, Frequency Selective Channel, Spatial Multiplexing, Transmit Diversity, Transmit Antenna Array (TxAA) , Antenna Selection Diversity, CQI Feedback.
