ABSTRACT:
Communication operation is performed with enhanced transmission efficiency by obtaining enhanced communication capacity through optimal allocation of transmission powers to individual MIMO channels obtainable by spatial multiplexing. A transmitter has a plurality of transmission antennas and a receiver has a plurality of reception antennas and perform spatial multiplex communication through transmission and reception with individual antenna weights being set. The transmitter varies the power allocation in units of a communication channel in correspondence to communication quality of the channel. The receiver uses a power allocation value of each communication channel that is estimated in accordance with a reception power of a pilot carrier included in user data after spatially separated. Thereby, the receiver returns the magnitude of the amplitude of a received signal in the signal spacing to an original magnitude, and performs an accurate demapping process.
