博弈论下基于串行干扰消除的功率控制算法
Power Control Algorithm Based on Serial Interference Cancellation in Game Theory
摘要
Abstract
In order to improve the system performance in cognitive wireless networks,meet the communication quality of pri-mary users and reduce the transmission power of secondary users,a power control algorithm based on non-cooperative game and non ideal serial interference cancellation algorithm is proposed in this paper.Firstly,a new utility function is designed according to the serial interference cancellation algorithm and cognitive wireless communication technology,combined with the channel state.Secondly,for the power control algorithm under the constraint of the utility function,the uniqueness and reachability of its Nash equilibrium solution are proved.The simulation results show that the algorithm can not only converge quickly,but also reduce the transmission power of secondary users and improve the signal to interference noise ratio on the premise of meeting the communica-tion quality of secondary users and primary users.Finally,the simulation results show that compared with the other three algo-rithms,the proposed algorithm has better anti background noise performance and higher operational stability.关键词
