H04L27/2014 - 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 phase changes in a piecewise linear manner during each symbol period, e.g. minimum shift keying, fast frequency shift keying
