| 摘 要： | 本文采用博弈论研究了多小区CDMA功率控制问题。证明了在时延约束条件下联合考虑功率和速率控制的纳什均衡的唯一性,提出了多小区的速率和功率更新算法。仿真表明,本文提出方法可以满足不同用户对速率和时延的不同要求,且系统中各个用户的吞吐量和数据的发送速率有了大幅度的提高。

| Abstract: | In this paper,we consider the power control things in a multi-cell CDMA system with the approach of the game theory. The unique Nash Equilibrium of the power and the transmission rate with the delay constraint is proved.And then we present the upda- ting algorithm of the power and rate.The simulation results show that the method we introduced can satisfied different needs for rate and transmission delay and improve the throughput and transmission rate greatly. |
