1. An integrated circuit comprising:
generation circuitry, which in operation, controls generating precoded signals of Z1(i) and Z2(i), a first pilot signal and a second pilot signal, wherein Z1(i) is generated by adding modulated signals of S1(i) and S2(i), Z2(i) is generated by adding a first rotated signal rotating a phase of the S1(i) by a first phase and a second rotated signal rotating a phase of the S2(i) by a second phase, i is different among symbols and is an integer greater than or equal to zero; and
transmission circuitry, which in operation, controls transmitting the precoded signals, the first pilot signal and the second pilot signal,
wherein a difference between the first phase rotating the S1(i) and the second phase rotating the S2(i) is π radian, and a difference between the first phase rotating the S1(0) and the first phase rotating the S1(1) is π/2 radian.
