Coding and Flow of Information in Communication Networks

现代通信系统必须在使用卫星、大规模计算机通信网络和局域网的系统上处理多用户问题。通常，要么涉及广播，要么涉及多个接入频道。主要关注的是可以达到什么通信速率，以及如何在这些速率附近实现可靠的信息传输。这项研究解决了通信网络中编码和信息流的一些基本问题。这些问题分为四个研究领域：多用户通信信道的编码；这些信道的检错编码；线性分组码的权重分布；以及通信网络的可达到的速率区域。

Modern communication systems must deal with the problem of multiple users on systems which use satellites, large-scale computer communication networks, and local area networks. Usually, either broadcasting or multiple access channels are involved. Major concerns are what communication rates can be achieved and how to achieve reliable transmission of information near these rates. This research attacks some fundamental problems in coding and the flow of information in communication networks. These problems fall into four research areas: coding for multiple-user communication channels; error detection coding for these channels; weight distribution of linear block codes; and achievable rate regions for communication networks.
