1. A transmission device comprising:

  • a first mapper configured to map a first bit stream of a first data series to generate a first modulated symbol stream;

    a second mapper configured to map a second bit stream of a second data series to generate a second modulated symbol stream, the first modulated symbol stream and the second modulated symbol stream being representable on a complex plane extending in a first direction and a second direction perpendicular to the first direction;

    a converter configured to convert the second modulated symbol stream in accordance with the first modulated symbol stream only in the first direction on the complex plane;

    a superposer configured to superpose the first modulated symbol stream and the second modulated symbol stream converted by the converter, at an amplitude ratio, to generate a multiplexed signal; and

    a transmitter configured to transmit the multiplexed signal.
