Samenvatting

This book introduces turbo error correcting concept in a simple language, including a general theory and the algorithms for decoding turbo-like code. It presents a unified framework for the design and analysis of turbo codes and LDPC codes and their decoding algorithms.

A major focus is on high speed turbo decoding, which targets applications with data rates of several hundred million bits per second (Mbps).
