An apparatus for transmitting a signal in a Multiple Input Multiple Output (MIMO) communication system includes determining transmission antennas to be used by a signal transmission apparatus depending on channel quality information received from a reception apparatus, encoding an input information data stream into a codeword using a coding scheme, mapping the codeword using a MIMO mapping scheme thereby generating at least one mapped symbol, modulating the mapped symbols into modulation symbols according to a modulation scheme, and performing transmission processing on the modulation symbols thereby generating transmission streams, and transmitting the transmission streams via the determined transmission antennas. |
