Today's wireless communication services have come a long way since the introduction of the first generation of cellular systems in the early 1980s. The demand for wireless access in high-speed multi-media applications, environmental monitoring and telemedicine has been increasing steadily. New generations of wireless systems and networks can only accommodate this demand by relying on better resource management and improved transmission technologies. It has been recognized that future wireless communication systems and networks will be based on the emerging technology of cooperative/relay communications. The concept of cooperative and relay communications is that nodes (or users) in a network cooperate to transmit data from a source to a destination. This technology has many potential advantages over conventional point-to-point communications, including configuration flexibility, better coverage, improved performance, higher capacity, etc. There have been extensive research activities in cooperative/relay communications after the publication of seminal papers by Sendonaris et al. (2003) and Laneman (2004). It is now understood that potential gains of cooperative/relay communications can only be realized when the right approach is applied to a specific application scenario. To bring cooperative/relay communications into practice, continued research efforts are still much needed. This research proposal shall look at practical methods and techniques for improving the reliability and/or capacity of wireless relay networks by allowing multiple transmissions to take place simultaneously over a common transmission medium. The key technical issue to be addressed is interference management, both at the relay and destination nodes. The proposed research includes both analysis and computer simulation to develop and evaluate performance of the new methods and techniques. The successes of the proposed research program should enhance Canada's competitive position in providing reliable and efficient transmission of information over wireless communication systems and networks.

自20世纪80年代初引入第一代蜂窝系统以来，今天的无线通信服务已经走过了漫长的道路。高速多媒体应用、环境监测和远程医疗对无线接入的需求一直在稳步增长。新一代的无线系统和网络只能依靠更好的资源管理和改进的传输技术来满足这种需求。人们已经认识到，未来的无线通信系统和网络将以新兴的合作/中继通信技术为基础。协作和中继通信的概念是指网络中的节点（或用户）合作将数据从一个源传输到一个目标。与传统的点对点通信相比，该技术具有许多潜在的优势，包括配置灵活性、更好的覆盖范围、改进的性能、更高的容量等。
