摘要
为解决CDMA系统中各用户与基站间距离的远近公平问题,提出了一种基于公平性考虑的非合作博弈功率控制算法。该算法综合考虑用户路径增益与发射功率等,设计了一种新的且存在唯一纳什均衡的代价函数,进而能够改善系统中的远近公平问题。仿真结果表明,与传统的功率控制算法相比,提出的功率控制算法具有用户发射功率降低,而且用户获得的SIR是远近公平的,并且用户获得的收益也是远近公平的优势。系统的远近公平问题得到了很好的改善。
For prepose to solve the far - near fairness in the CDMA system, this paper proposes a power control algorithm based on non-cooperative game. This algorithm gives comprehensive consideration of path gain and transmission power of the terminal A new cost function with the existence of unique Nash equilibrium is designed, and thus the far-near fairness in the system is improved. Simulation indicates the fairness improvement of network resource allocation and the lowering of transmission power of the terminal.
