Abstract: A transmitter in an MIMO(Multi-Input Multi-Output) system and a data transmitting method thereof are provided to generate greater performance gain than an existing open loop V-BLAST system because of using a different modulation method and different power by transmitting antennas. A transmitter in an MIMO(Multi-Input Multi-Output) system comprises the followings: a memory(201) which stores a modulation method by antennas and a power allocation coefficient; a modulation unit(202) which separately modulates transmission data according to the modulation method by antennas stored in the memory if the transmission data is inputted; and a power control unit(204) which controls the power of each transmission data modulated in the modulation unit according to the power allocation coefficient by antennas stored in the memory and transmits the transmission data through a corresponding antenna.
