Baud-rate data-aided timing recovery for digital magnetic recording systems with quadra-phase modulation code

Quadra-phase (QP) is a binary modulation code with desirable features for use in digital magnetic recording. The paper describes simple data-aided timing acquisition and tracking techniques for QP that do not involve any oversampling and automatically achieve word synchronization. >
