METHOD FOR CANCELING INTERFERENCE IN SUPER RESOLUTION OPTICAL DISC

摘要

PURPOSE: A method for canceling interference in a super-resolution optical disc is provided to minimize a read RF signal and a signal corresponding to data of fixed pattern by controlling the weighted value. CONSTITUTION: A method for canceling interference in a super-resolution optical disc comprises a step of pre-processing a signal outputted from a recording medium, a step of processing the pre-processed signal through a neural network based nonlinear equalizer, and a step of restoring data from the signal processed through a vitervi decoder. A tangent sigmoid function and a linear function are used as active functions for the hidden layer and output layer of the nonlinear equalizer.
