System for re-establishing the transmission quality of a link including amplifier equipments in the event of failure of one or more amplifier equipments

摘要: A system for re-establishing the transmission quality of a digital information link including amplifier equipments in event failure one or more includes, associated with at least equipments, gain control device varying equipment order to compensate deterioration receive signal-to-noise ratio following other equipment. An error corrector coder send end operates on be transmitted and an decoder received information. The code used by reduces eliminate residual errors receiving not compensated gain.
