1. A transmission method comprising:

  • generating a coded block made up of a plurality of bits by using a predetermined error correction block coding scheme;

    generating, for each of a plurality of slots, a first transmission signal z1 and a second transmission signal z2 from the coded block; and

    transmitting the first transmission signal z1 and the second transmission signal z2 respectively from a first antenna and a second antenna at the same time at the same frequency,the transmission signal generation including;

    generating, for each of the plurality of slots, a first modulated signal s1 and a second modulated signal s2 from the coded block;

    with respect to the first modulated signal s1 and the second modulated signal s2, applying precoding expressed by a fixed matrix F and performing a phase change while regularly varying a scheme of phase change for each of the plurality of slots,the matrix F being expressed as;
