H04L27/2092 - CPC Classification

Classification description:

Modulated-carrier systems; Phase-modulated carrier systems, i.e. using phase-shift keying; Modulator circuits; Transmitter circuits for discrete phase modulation, e.g. in which the phase of the carrier is modulated in a nominally instantaneous manner with digital generation of the modulated carrier (does not include the modulation of a digitally generated carrier)
