ITR: Collaborative Research: Towards Practical Graph -Based Coding Schemes for Realiable Wireless Communications

点击翻译按钮获取中文摘要

This project focuses on the physical layer of digital communicationsystem design - in particular on the design of graph-based errorcontrol coding techniques for noisy, fading channels, such as thoseencountered in wireless communication systems. The researchaddresses those issues that have made practical implementation ofgraph-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 schemesincorporating these new code constructions in order to "fatten thebit pipe" in high data rate applications.The adaptation of these new coding schemes for use in the fadingenvironment that characterizes wireless channels.
