PROBLEM TO BE SOLVED: To provide a method for generating a plurality of precoded signals to be simultaneously transmitted from a plurality of base band signals with the same frequency.SOLUTION: The precoding method includes: applying power change against a first modulation signal s1 and a second modulation signal s2; and applying precoding processing to the power changed first modulation signal s1 and second modulation signal s2 to generate a first transmission signal z1 and a second transmission signal z2. When any of N precoding matrices F[i] is selected, average power of the first transmission signal z1 and average power of the second transmission signal z2 are equal.SELECTED DRAWING: Figure 108 |
