PROBLEM TO BE SOLVED: To provide a precoding MIMO system wherein a weighting factor is given to a transmission stream to suppress an increase in PAPR. SOLUTION: An amplification ratio is defined for weighting factors (U<SB>1, 1</SB>and U<SB>1, 2</SB>, U<SB>2, 1</SB>and U<SB>2, 2</SB>) of individual transmission streams to be multiplexed on either one of a plurality of transmission antennas.
