Efficient Configuration of Multi-Branch Wireless Cooperative Networks

One of the challenging issues in the development of wireless cooperative diversity networks is the design of practical algorithms for link configuration. In this paper, we consider the problem of selecting the most suitable relay terminals in a multi- branch wireless amplify-and-forward cooperative network, so that the overall symbol error rate is minimized. Simulation results which compare the performance of the proposed algorithm to the case when the relay nodes are selected randomly are presented which demonstrate the effectiveness of the proposed algorithm.
