| Abstract: | The use of cooperative communications technology can effectively improve performance of the wireless communication systems,particularly the systems that own single-antenna nodes.The allocation of the transmission power will affect the performance of the system,so rational distribution of the power between the source node and the relay node will improve the utilization of power.In this paper,the problem of power distribution between source and relay based on the instantaneous channel information was studied.... |
