Optimum Relay Location in Cooperative Communication Networks with Single AF Relay
Lei Xu, Hong-Wei Zhang, Xiao-Hui Li, Xian-Liang Wu
Abstract: In recent years cooperative diversity has been widely used in wireless networks. In particular, cooperative communication with a single relay is a simple, practical technology for wireless sensor networks. In this paper, we analyze several simple network topologies. Under the condition of equal power allocating, the optimum relay location of each network topology are respectively made sure by using symbol error rate (SER) formula. And these types of topologies are compared, the analysis results show that, linear network topology has the best system performance, the system performance of isosceles triangle topology is better than that of equilateral triangle topology.
Keywords: Relay Location, Cooperative Communication, AF (Amplify and Forward), Topology
