H04L27/186 - CPC Classification

Classification description:

Modulated-carrier systems; Phase-modulated carrier systems, i.e. using phase-shift keying in which the information is carried by both the individual signal points and the subset to which the individual signal points belong, e.g. coset coding or related schemes
