1. A transmitting apparatus comprising:
signal processing circuitry configured to:
generate a first frame and a second frame; and
apply a phase change to the second frame to generate a second phase-changed frame, the phase change not being applied to the first frame; and
a transmitter configured to transmit the first frame and the second phase-changed frame from a first antenna and a second antenna, respectively, wherein in the phase change:
a first phase change value is applied to a first symbol in the second frame;
a second phase change value is applied to a second symbol adjacent to the first symbol in a time direction in the second frame;
a third phase change value is applied to a third symbol adjacent to the first symbol in the second frame;
the second phase change value is different from the first phase change value; and
the third phase change value is different from the first phase change value.
