Abstract

This project focuses on the physical layer of digital communication system design - in particular on the design of graph-based error control coding techniques for noisy, fading channels, such as those encountered in wireless communication systems. The research addresses those issues that have made practical implementation of graph-based coding techniques problematic. Those issues include: The development of LDPC and turbo codes with algebraic structure, suitable for high speed implementation. The development of LDPC and turbo codes with moderate block length, suitable for practical real-time applications. The design of bandwidth efficient coded modulation schemes incorporating these new code constructions in order to "fatten the bit pipe" in high data rate applications. The adaptation of these new coding schemes for use in the fading environment that characterizes wireless channels.
