Summary:
In this paper, we investigate the performance of perpendicular recording channel for dc-full and dc-attenuation partial response targets under the environment of electronics noise and jitter noise. We compare the performance of partial-response maximum-likelihood (PRML) and noise-predictive maximum?likelihood (NPML) detector for both types of targets. The NPML system is more suited for dc-attenuation targets, whereas the dc-full targets are suited to PRML system at low jitter noise.
