摘要: A method and system for cross-talk cancellation in a three-spots push-pull tracking error signal an optical disc is disclosed. (TES) determined from plurality of signals (PPa, PPb, PPC). noise (N) at least two the signals. The filtered first filter (406). subtracted to produce resultant signal(TESXTC), wherein coefficients (406) are selected by minimizing cross-correlation between (TESXTC ).
