Wireless networking constitutes an important component of future information technology applications for both military and civilian purposes ranging from ad-hoc and sensor networks deployed in a battle-field to cellular networks with a very strong infrastructure. In order to design, implement and deploy highly reliable wireless networks, it is of utmost importance to address the presence of interference from other users in the system. In existing designs, interference is either avoided by a carefully chosen networking protocol (e.g. through time-division, space-division, frequency-division), or it is controlled to be near an acceptable level (e.g. through code-division). While simplifying the implementation, both of these commonly taken approaches are far from being optimal, and for reliable and efficient wireless networks of the future, a different look at the problem of handling the interference is needed.This research aims to develop explicit and practical coding/modulation solutions for multi-user communication channels, and to assess the possible gains with the enhanced physical-layer designs through end-to-end network simulation studies. In particular, a number of problems ranging from design of coding/modulation schemes for wireless interference channels, and two-way relay channels, to practical signaling for finite-input finite-output multi-user links are addressed. Both long block length coding/modulation solutions aiming at near capacity (or capacity bound) operation as well as short block length designs for delay sensitive applications are explored. Through these research activities, the project directly contributes to design and development of reliable wireless networks managing interference in an efficient manner, and to the field of general multi-user communications in a fundamental way. The project also integrates research and education generating many opportunities for undergraduate students to be involved in these activities.

无线网络构成了未来军事和民用信息技术应用的重要组成部分，从部署在战场上的自组织和传感器网络到具有非常强大基础设施的蜂窝网络。为了设计、实现和部署高度可靠的无线网络，解决系统中其他用户的干扰是至关重要的。在现有设计中，干扰或者通过仔细选择的联网协议（例如，通过时分、空分、频分）来避免，或者被控制为接近可接受的水平（例如，通过码分）。在简化实现的同时，这两种常用的方法都远远不是最佳的，并且对于未来可靠和高效的无线网络，需要对处理干扰的问题有不同的看法。本研究旨在为多用户通信信道开发明确和实用的编码/调制解决方案，并通过端到端网络仿真研究评估增强物理层设计的可能收益。特别是，从无线干扰信道的编码/调制方案的设计，和双向中继信道，有限输入有限输出多用户链路的实际信令的一些问题得到解决。长块长度的编码/调制解决方案，旨在近容量（或容量界）的操作，以及短块长度的延迟敏感的应用程序的设计进行了探讨。通过这些研究活动，该项目直接有助于设计和开发以有效方式管理干扰的可靠无线网络，并从根本上促进一般多用户通信领域。该项目还整合了研究和教育，为本科生提供了许多参与这些活动的机会。
