PRECODING METHOD AND PRECODING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a technique of generating, from plural base band signals, plural pre-coded signals to be simultaneously transmitted at the same frequency.SOLUTION: Power revision is applied to a first modulation signal 307A and a second modulation signal 307B. A power-revised first modulation signal 10702A and a power-revised second modulation signal 10702B are subjected to precoding processing to generate a first transmission signal 309A and a second transmission signal 309B. Even when any of precoding matrixes of N is selected, the average power of the first transmission signal 309A is equal to the average power of the second transmission signal 309B.SELECTED DRAWING: Figure 108
