METHOD AND SYSTEM FOR PROVIDING TIMING RECOVERY IN AN OPTICAL SYSTEM

摘要

The invention regards a new threshold crossing timing recovery scheme for use in high capacity optical disc systems. The timing error of a timing error detector is multiplied with a weighing function. This scheme effectively increases the robustness of the optical system against data- induced jitter, which is considered to be the dominant disturbance of the timing recovery as the capacity of the optical discs is high. The invention furthermore describes a number of examples of possible weighing functions.
