Design and analysis of cooperative-diversity wireless networks

对用于下一代无线系统的高效技术的需求日益增长。因此，现在是解决能够在传输速率和服务质量方面彻底改变无线通信系统的新技术的时候了。协作分集是一种非常有前途的技术，有望成为未来无线系统的基础技术之一。协作分集的主要概念是源节点和目的节点之间的中间节点可以转发源信号以在目的地处获得相同信号的多个副本。组合这些多个副本可以带来许多好处，如更好的信号质量、更好的覆盖范围和更高的容量。然而，合作分集也带来了一些挑战和复杂性。这项研究计划要解决的主要问题如下：

There is a growing demand for efficient techniques for next generation wireless systems. Hence, it is timely to address new technologies that can revolutionize wireless communication systems in terms of transmission rates and quality of service. Cooperative diversity is a very promising technology which is expected to be one of the underlying technologies for future wireless systems. The main concept of cooperative diversity is that intermediate nodes between the source and destination nodes can forward the source signal to obtain multiple copies of the same signal at the destination. Combining these multiple copies can bring many benefits such as better signal quality, improved coverage and higher capacity. However, cooperative diversity also brings some challenges and complexities. The main issues to be addressed in this program of research are the following:
