说明：  本文研究了有限反馈下基于博弈论的联合功率分配与反馈速率控制优化问题。通过建立新的博弈模型，证明了其纳什均衡的存在性。同时，根据功率与反馈速率的关系，提出了一种迭代算法，可快速收敛到博弈不动点。仿真结果表明，联合优化算法的性能优于单单考虑反馈速率的算法。(In this paper, under the limited feedback joint power allocation based on game theory and feedback rate control optimization problems. Through the establishment of a new game model proved its existence of Nash equilibrium. Meanwhile, according to the relationship between power and the feedback rate proposed an iterative algorithm can quickly converge to a fixed point game. Simulation results show that the performance of joint optimization algorithm is superior to just consider the feedback rate of the algorithm.)
