Read circuit of a disk drive system and method of signal processing thereof |
摘要 |
A read circuit of a disk drive system that adaptively reduces signal-dependent noise including a sequence detector, a signal-dependent adaptive engine and a signal-dependent post-processor. The sequence detector recovers a data sequence from equalized data. The signal-dependent adaptive engine generates signal-dependent coefficients, a mean value and a standard deviation of a signal-dependent error. The signal-dependent post-processor corrects the signal-dependent error.
