Interference Management in Wireless Relay 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取得了长足的进步。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有依靠更好的资源管理和改进的传输技术才能满足这一需求。人们已经认识到，未来的无线通信系统和网络将基于新兴的协作/中继通信技术。协作和中继通信的概念是网络中的节点(或用户)协作将数据从源传输到目的地。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、更高的性能、更大的容量等。

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.
