Abstract
A system and method for transmitting an analog signal. The analog signal is converted into complex numbers such that two successive audio samples respectively form a real part and an imaginary part of a respective complex number. The complex numbers are then dispersed in a time-frequency space. The complex numbers are then modulated through a digital modulator into temporal signals and the temporal signals are output for transmission. Thereby, a digital modulator conventionally used for modulating digital input signals can operate for the transmission of an analog signal.
