METHOD AND APPARATUS FOR REGENERATING DATA

摘要

The invention provides a method and apparatus for efficiently regenerating an incoming data signal at a sampling point which is continually optimized independently of the regeneration process. While the incoming data signal is being regenerated in a regeneration unit, the invention uses a monitoring unit for concurrently optimizing the slicing threshold and sampling phase used in the regeneration unit without disturbing the on-going data regeneration. The invention uses a master-slave arrangement to regenerate the incoming data signal whereby the regenerating unit is updated with a new slicing threshold and sampling phase only after the new slicing threshold and sampling please are fully optimized by the monitoring unit. In this way, the data regeneration can proceed unaffected by the optimization of the slicing threshold and sampling phase which, as a result can be continuously optimized without inducing any errors into the regenerated data.
