H04L27/2042 - 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 a single or unspecified number of carriers with more than two phase states

Sub-classes:

H04L27/2046 » {in which the data are represented by carrier phase} 11
H04L27/205 » {in which the data are represented by the change in phase of the carrier} 27
