Partial response equalizer performance in digital magnetic recording channels
D.J. Tyner, John G. Proakis · IEEE Transactions on Magnetics · 1993
The performance of partial response linear and decision-feedback equalizers is evaluated for a digital magnetic recording channel having a symmetric pulse response, and a magnetic recording channel having an asymmetric pulse response. Both linear and decision-feedback equalizers are considered based on the zero-forcing criterion. Symbol-by-symbol detection and maximum-likelihood sequence estimation are investigated. The performance of the detection methods is evaluated both analytically and by Monte Carlo simulation.>
