Abstract
A receiving device for angle-modulated signals performs the channel selection in a digital manner rather than an analog manner. A receive signal is preferably initially converted to an intermediate frequency band, filtered and A/D converted. The receive signal is subsequently converted to the baseband and channels are selected in a digital manner through the use of a digital complex multiplier before the receive signal component of the selected transmission channel is demodulated and the corresponding symbols are detected through the use of a differential demodulator.
