Abstract
In a maximum likelihood sequence detector for symbol sequences which were equalized in a PR4 equalizer, noise prediction means ( ) are provided including infinite impulse response (IIR) filtering, which have noise-whitening capabilities and are imbedded into the maximum likelihood detection process. The resulting INPML detector ( ) can be implemented in digital or analog circuit technology. In addition, a DC-notch filter ( ) and a stochastic gradient procedure can be provided for DC offset compensation and for MR head or signal asymmetry compensation.
