Abstract:
1. A transmission method for generating a plurality of precoded signals and transmitting the plurality of precoded signals from a plurality of antennas in the same frequency at the same time, the transmission method comprising, in the generation of the plurality of precoded signals, the steps of: selecting one matrix from among N matrices F[i] by hopping between the matrices, for each of a plurality of slots, where i is an integer no less than 0 and no more than N−1, and N is an integer 3 or greater, the N matrices F[i] each defining a precoding process that is performed on a plurality of baseband signals; generating a first baseband signal s generating a first precoded signal z the first baseband signal s the N matrices F[i] satisfy: where λ represents an arbitrary angle, α represents a positive real number other than 1, θ where x and y are any integers no less than 0 and no more than N−1 and satisfy x≠y, and a first slot of the first baseband signal s
