Timing recovery techniques for digital recording systems

 This thesis is devoted to the development of timing recovery techniques for digital recording systems. The thesis begins with a detailed review and discussion of timing recovery structures, requirements, performance measures, timing error detector (TED) algorithms, and timing acquisition issues. The main contributions include five parts. The first part examines the timing sensitivity of read channel detectors, and develops a new analytical approach for evaluating the performance under static and random timing errors. The second part examines the TED efficiencies, develops an improved TED for jitter minimization, and studies optimality issues for timing acquisition. The third part investigates false lock and hang up problems, and develops two novel acquisition techniques. The fourth part presents the timing recovery loop design and implementation for an experimental read channel detector. The fifth part develops a new asynchronous equalizer adaptation structure with fully digital interpolative timing recovery (ITR) for digital optical recording systems.
