Abstract:
1. A reception method for receiving a first signal and a second signal precoded and transmitted by a transmission apparatus, the reception method comprising: receiving the first signal and the second signal, wherein the first signal and the second signal are generated by using one of a plurality of precoding matrices, while regularly hopping between the precoding matrices, to precode a first modulated signal and a second modulated signal modulated in accordance with a modulation method, the first modulated signal and the second modulated signal being composed of an in-phase component and a quadrature component, for a first symbol that is a data symbol used to transmit data of the first modulated signal and a second symbol that is a data symbol used to transmit data of the second modulated signal, when a first time and a first frequency at which the first symbol is to be precoded and transmitted match a second time and a second frequency at which the second symbol is to be precoded and transmitted, two third symbols adjacent to the first symbol in the frequency domain are both data symbols, then the first signal is generated by precoding the first symbol, and the two third symbols, the first symbol being precoded with a different precoding matrix than each of the two third symbols, the first signal and the second signal each include a plurality of data blocks, the reception method further comprising: the first signal and the second signal include a control symbol, and the reception method further comprising:
