Abstract (en)

[origin: WO2007131864A1] In the signal quality detector (7, 8, 10), a 3R-regenerated electrical received signal (REDS) is correlated with a non-regenerated received signal (EDS). The result is a direct measure of the correlation between non-regenerated and regenerated received signals and can be used for controlling a PMD-compensator (3).
