1. An integrated circuit comprising:
circuitry, which, in operation, controls
performing a precoding process on first modulated symbols s1(t) and second modulated symbols s2(t) to generate first precoded symbols z1(t) and second precoded symbols z2(t), t being an integer starting from 0 and incrementing in steps of 1; and
transmitting the first precoded symbols z1(t) and the second precoded symbols z2(t) from different antennas;
wherein the precoding process is expressed by the following Equation 1:

OG Complex Work Unit Math
θ changes in turn according to t within a period N, θ is a value expressed in radians, and Iz1(t), Iz2(t), Is1(t), Is2(t) are in-phase component of z1(t), z2(t), s1(t), s2(t), respectively, and Qz1(t), Qz2(t), Qs1(t), Qs2(t) are quadrature component of z1(t), z2(t), s1(t), s2(t), respectively.
