| 摘 要： | 在码分多址(CDMA)系统中引入博弈论进行更优化的功率控制已成为近年来蜂窝移动通信研究的热点，但传统静态博弈论下的功率控制算法收敛速度不够快，且迭代过程中功率波动幅度较大。针对问题，提出了将动态博弈引入CDMA系统功率控制算法。通过仿真表明，提出的动态博弈功率控制算法与传统静态博弈论下分布式功率控制算法相比，在保证系统总的功率相同的情况下，能大幅度的提高功率的收敛速度。

| Abstract: | Optimal power control with game-theory has been a hot research topic in code division multiple access (CDMA) system. However, the convergence speed of the power control algorithm based on traditional static game-theory is not fast enough and the power fluctuation is large during the iterative process. In order to solve this problem, dynamic game-theory is introduced into CDMA system power control algorithm. The simulation results show that the proposed algorithm, compared with the distributed power control algorithm based on the traditional static game theory, can improve the convergence speed obviously with the same power spending. |
