摘要 该文针对蜂窝模式和端到端模式混合网络,提出了一种端到端分布式功率控制方法。该算法以最大化系统频谱效率为目标,以凸优化工具为基础,提出了分布式功率控制的具体算法。在算法设计中考虑了混合网络中不同通信模式之间的有害干扰,提出了有效的干扰避免方法,从而提高了系统吞吐量。仿真结果对算法的收敛性和性能进行了验证。 A distributed power control algorithm in hybrid cellular and Peer-to-Peer（P2P） network is proposed.In the objective of overall system spectrum efficiency maximization,a distributed power control scheme of P2P transmission in the hybrid system model is devised based on the tools of convex optimization.The algorithm considers the harmful interference between cellular sub-system and P2P sub-system,and provides effective interference avoidance mechanism,thus improves the total system throughput.Simulation results prove the convergence and performance of the proposed scheme.
