H04L27/2032 - 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

Sub-classes:

H04L27/2035 » {using a single or unspecified number of carriers} 36
H04L27/2053 » {using more than one carrier, e.g. carriers with different phases} 73
H04L27/2092 » {with digital generation of the modulated carrier (does not include the modulation of a digitally generated carrier)} 33
