H04L27/2067 - 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 using more than one carrier, e.g. carriers with different phases using a pair of orthogonal carriers, e.g. quadrature carriers with more than two phase states
