H04L27/201 - CPC Classification

Classification description:

Modulated-carrier systems; Phase-modulated carrier systems, i.e. using phase-shift keying; Modulator circuits; Transmitter circuits for continuous phase modulation in which the phase change within each symbol period is constrained in which the allowed phase changes vary with time, e.g. multi-h modulation
