Patent ID: 8532219

Claim:
A transmitting apparatus comprising: a signal processing section that generates a first modulation symbol sequence by changing an amplitude of a modulation symbol sequence where first transmission data is mapped using a first mapping pattern of a predetermined modulation scheme and generates a second modulation symbol sequence by changing an amplitude and a mapping pattern of a modulation symbol sequence where second transmission data is mapped using the first mapping pattern; and a plurality of antennas that transmit the first modulation symbol sequence and the second modulation symbol sequence, respectively, in a same frequency band and at a same time, wherein: the second modulation symbol sequence is generated using a second mapping pattern where a phase of the first mapping pattern is changed to a predetermined direction per the second modulation symbol, the first mapping pattern arranges a first bit set which comprises a plurality of bits to a first signal point on an IQ plane, the second mapping pattern arranges the first bit set to a second signal point on the IQ plane, and the first bit set is all possible combinations of the plurality of bits.
