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.

现代通信系统必须处理使用卫星、大规模计算机通信网络和局域网的系统上的多用户问题。 通常，涉及广播或多址信道。 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；这些通道的错误检测编码；线性分组码的权重分布；以及通信网络可达到的速率区域。
