Abstract :
To satisfy future demands of wireless systems, one of key technologies is to improve the robustness of wireless transmission. In this paper, three cooperative schemes are proposed with the antennas sharing among multiple nodes to achieve cooperative diversity in wireless networks. The proposed schemes could be applied in two practical relay scenarios in which each node has one antenna or two antennas respectively. The simulations show that these schemes can achieve better performance to combat the channel corrupt. And the techniques can be applied in wireless cooperative communications.
