Abstract:
1. A transmission method comprising: generating a first transmission signal and a second transmission signal from a first modulation signal and a second modulation signal in accordance with a modulation method, the first modulation signal and the second modulation signal being composed of an in-phase component and a quadrature-phase component, a relationship between symbols of the first modulation signal and symbols of the first transmission signal and a relationship between symbols of the second modulation signal and symbols of the second transmission signal each being represented by any one of a plurality of precoding matrices; transmitting the first transmission signal from one or more first outputs; and transmitting the second transmission signal from one or more second outputs, wherein when (i) a first symbol is a data symbol used to transmit data of the first modulation signal and the second modulation signal, (ii) a second symbol and a third symbol that are adjacent to the first symbol in a frequency domain are both data symbols, and (iii) a fourth symbol and a fifth symbol that are adjacent to the first symbol in a time domain are both data symbols, a precoding matrix that corresponds to the first symbol is different from any of precoding matrices that correspond to the second symbol, the third symbol, the fourth symbol and the fifth symbol.
