This book is a useful tool for researchers in both academia and
industry who are interested in improving the performances of
magnetic recording systems using new coding schemes. Coding and
Iterative Detection for Magnetic Recording Channels proposes
several new approaches for enhancing the performance of magnetic
recording systems by coding and interpolated timing recovery. It
provides a tutorial introduction to turbo codes, LDPC codes and
their iterative detection schemes. The main emphasis, however, is
placed on the simplification of the detector structures for the
implementation of various codes. Chapter 1 introduces the model for
magnetic recording channels and the challenges to the read channel
detector designs. Chapter 2 discusses the turbo codes and the turbo
equalization structure for ISI channels. Chapter 3 summarizes the
major concepts of LDPC codes and their iterative detection
algorithms based on belief propagation. Chapter 4 introduces the
Decision Aid Equalization (DAE) structure to simplify iterative
detection for ISI channels. Chapter 6 proposes an interpolated
timing recovery scheme that facilitates symbol timing recovery by
its re-sampling' capability. The combination of the above-mentioned
chapters leads to a new structure for implementing iterative
detection on recording channels. Chapter 5 deviates from iterative
detection to propose a simple code, the Interleaved Parity Check
(IPC) code, and its reduced-complexity decoder, which is considered
practical for implementation with currently available integrated
circuit technology. Chapter 7 summarizes the book with a discussion
on future research topics in this field. Coding and Iterative
Detection for MagneticRecording Channels is a valuable reference
for researchers and design engineers working on signal processing
and coding for magnetic recording channels. It may also be used as
a graduate text for courses on turbo codes.
