The promise of essentially error-free information transmission is a cornerstone of digital communications. Next-generation applications demand increasingly effective error correction, yet traditional systems fall well short of fundamental capacity limits established some fifty years ago. Exciting breakthroughs in the mid-1990s delivered capacity-approaching codes on graphs employing iterative decoding algorithms, including low-density parity-check (LDPC) codes. This project applies techniques from discrete mathematics to design structured LDPC coding schemes for widespread implementation. Outcomes of this research will be new LDPC codes, encoding algorithms and analysis techniques for applications including wireless networks, data storage and Internet communications.

基本上无差错的信息传输是数字通信的基石。下一代应用程序需要越来越有效的纠错，但传统系统远远低于大约50年前建立的基本容量限制。20世纪90年代中期的令人兴奋的突破提供了采用迭代解码算法的图上接近容量的代码，包括低密度奇偶校验（LDPC）码。本计画应用离散数学的技术来设计结构化的低密度奇偶校验编码方案，以供广泛应用。这项研究的成果将是新的LDPC码，编码算法和分析技术的应用，包括无线网络，数据存储和互联网通信。
