Claim 6:
7. A reception method comprising:
receiving a multiplexed signal on which a first modulated symbol stream and a second modulated symbol stream are superposed at an amplitude ratio in a state where the first modulated symbol stream is not converted, the first modulated symbol stream having a first in-phase component and a first orthogonal component, the second modulated symbol stream having a second in-phase component and a second orthogonal component, the second modulated symbol stream being converted 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

deriving at least one of the first modulated symbol stream or the second modulated symbol stream from the multiplexed signal.
