Assignee: PANASONIC INTELLECTUAL PROPERTY CORPORATION OF AMERICA
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A transmission device comprising:
a processor configured to:
generate a first modulated symbol stream, the first modulated symbol stream having a first in-phase component and a first orthogonal component;
generate a second modulated symbol stream, the second modulated symbol stream having a second in-phase component and a second orthogonal component;
convert the second modulated symbol stream such that:
(i) a polarity of the second in-phase component is inverted if a polarity of the first in-phase component is positive; and
(ii) a polarity of the second orthogonal component is inverted if a polarity of the first orthogonal component is positive; and

superpose the first modulated symbol stream and the second modulated symbol stream converted, at an amplitude ratio, to generate a multiplexed signal in a state where the first modulated symbol stream is not converted; and

a transmitter configured to transmit the multiplexed signal.
