DIFF Subgroup
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.
