H04L 27/233

using non-coherent demodulation

Introduced: January 1995

Full Title

Full titles differ between systems:

IPC:

Modulated-carrier systems > Phase-modulated carrier systems, i.e. using phase-shift keying > Demodulator circuits; Receiver circuits > using non-coherent demodulation

CPC:

Modulated-carrier systems > Phase-modulated carrier systems, i.e. using phase-shift keying (H04L27/32 takes precedence) > Demodulator circuits; Receiver circuits > using non-coherent demodulation

Of 5 combined children, 0 exist in both systems.

5 codes are CPC-only extensions.
