  • Sector based timing recovery for a readback signal
    Patent number: 7511909
    Abstract: A method and a signal processing unit are proposed, for converting an asynchronous discrete-time signal to a synchronous discrete-time signal by performing sector-based timing recovery. The timing recovery includes aligning an initial portion of the asynchronous discrete-time signal to a first portion of a predetermined signal, and a later portion of the asynchronous discrete-time signal to a second portion of a predetermined signal. Optionally, the method and signal processing unit further perform sector based gain control, and sector-based removal of any dc component.
