Abstract
A receiver for a hard disk drive system includes an analog front end module configured to sample a read-back signal and to output a digital read-back signal. An equalizer module is configured to generate a data vector based on the digital read-back signal. A detector module is configured to generate a decision vector based on the data vector. A re-timing module is configured to generate a first revised data vector based on the data vector and the decision vector. The re-timing module re-samples a plurality of samples in the data vector in a non-sequential time order to generate the first revised data vector. An inter-track interference (ITI) cancellation module is configured to remove ITI from the first revised data vector and to generate a second revised data vector.
