摘要:
A system for removing low frequency offset distortion from a digital signal, the system comprising an analog-to-digital converter to convert an analog frequency signal associated with an optical storage medium to a digital frequency signal; an equalizer to equalize the digital frequency signal; an estimator to estimate a low frequency offset distortion of the digital frequency signal; a compensator to substantially cancel the low frequency offset distortion of the digital frequency signal from the equalized digital frequency signal using the estimate; and a decoder to decode the equalized digital frequency signal having the low frequency offset distortion substantially cancelled therefrom.
