Abstract:
A transmission apparatus includes M signal processors that respectively generate modulated signals directed to M reception apparatuses, M being an integer equal to or greater than 2, and an antenna section. Each signal processor modulates a first bit sequence made up of two bits to generate a first modulated signal and a second modulated signal, and modulates a second bit sequence made up of other two bits to generate a third modulated signal and a fourth modulated signal, in a case of transmitting multiple streams to a corresponding one of the M reception apparatuses. The antenna section includes a first antenna that transmits the first modulated signal and the third modulated signal and a second antenna that transmits the second modulated signal and the fourth modulated signal. At least either the signals transmitted from the first antenna or the signals transmitted from the second antenna are phase-changed signals.

Claim (Index 1):
A transmission apparatus, comprising:\n determining circuitry, which, in operation, determines whether a phase change before precoding is enabled or not; a modulation mapper, which, in operation,\n when the determining circuitry determines that a phase change before precoding is enabled, modulates a bit sequence to generate a symbol sequence to which a first phase change before precoding is applied, an amount of the first phase change before precoding being cyclically switched; and \n when the determining circuitry determines that a phase change before precoding is not enabled, modulates a bit sequence to generate a first symbol sequence and a second symbol sequence; \n a precoder, which, in operation,\n when the modulation mapper outputs the symbol sequence to which the first phase change before precoding is applied, performs precoding on the symbol sequence to generate a first precoded signal and a second precoded signal, wherein a second phase change is applied to the second precoded signal; and \n when the modulation mapper outputs the first symbol sequence and the second symbol sequence, performs precoding on the first symbol sequence and the second symbol sequence to generate a third precoded signal and a fourth precoded signal, to which a third phase change and a fourth phase change are applied, respectively; and \n a transmitter, which, in operation, transmits the first precoded signal and the second precoded signal or transmits the third precoded signal and the fourth precoded signal.
