PROBLEM TO BE SOLVED: To provide a wireless relay apparatus and a wireless relay method allowing to enlarge a relay-allowed area of a receiving station when multistream wireless communication is relayed between a transmission station and a receiving station. SOLUTION: M received signals received by each of receiving antennas in the relay apparatus are subjected to orthogonal transformation and phase rotation so that M output signals having the same power level are obtained. Accordingly, each of the power amplifiers which power-amplifies the output signals is set to an operation point producing the most efficient high output. Accordingly, the sum total of the transmission power of the relay station becomes large, and thus a relay-allowed area of the receiving station is enlarged. COPYRIGHT: (C)2011,JPO&INPIT |
