1. A communication device comprising circuitry configured to
modulate a four-dimensional input signal by combining four real-valued signal components of the four-dimensional input signal into a transformed signal and multiplying the transformed signal by carrier signals using two different carrier frequencies to obtain a transmit signal, and
transmit the transmit signal.
