DEFINITION

Classification: 375/274

Minimum shift keying:

(under subclass 272) Subject matter wherein the difference between the mark and space frequencies is at the minimum value still presenting orthogonality (zero cross-correlation) between the mark and space signals and thus providing for efficient detection of the data.

(1) Note. Continuous phase is maintained at the mark-space transitions.
