ABSTRACT:
A transmission bit and transmission power distributing method that can reduce the arithmetic amount in a multiantenna-input/multiantenna-output (MIMO) wireless communication system. This method comprises steps of calculating a signal-to-interference-noise ratio (SINR) gain after MIMO detection of each of transport substreams (S601, S602); optimizing, based on the acquired SINR gain, a transmission bit and transmission power distribution in the space domain for all transport substreams on a particular subcarrier in the frequency domain, thereby deciding a transmission bit and transmission power distribution parameters (S603, S604); and optimizing a transmission bit and transmission power distribution for adjacent subcarriers, by sequentially using the transmission bit and transmission power distribution parameters distributed on the subcarrier for which the transmission bit and transmission power distribution parameters have been decided (S605to S610).
