Abstract
In a phase-modulated communication system utilizing voice-band communication channels wherein phase-jumps may be experienced, a phase-jump detector indicates the occurrence of such phase-jumps. A phase-jump corrector responds to the persistence of a phase-jump condition by correcting for it without requiring shut-down and complete reequalization of the transmission channel. Monitoring of the incoming signal for phase-jump occurrence provides a convenient signal quality indication that represents the magnitude of the error in the X and Y components of each received symbol.
