摘要:
该文针对CDMA系统中的多业务处理的飞速发展，采用非合作博弈方法来实现系统速率与功率联合控制。将速率控制和功率控制分别等效为一个非合作博弈过程，并且针对传统算法收敛速度慢和非合作博弈算法远近不公平的缺点，考虑用户所受干扰大小以及信干噪比误差，提出一种改进的代价函数，将其应用到速率效用函数中。证明了联合算法NASH均衡的存在性和唯一性，通过仿真表明，用户通过较低的功率获得了较高的传输速率，且具有较快的收敛速度，公平性问题也得到了改善
Abstract:
Due to the rapid development of multimedia services, use game theory to achieve joint control of power and rate in CDMA sys tem. The power and rate control problem is equivalent to be a non-cooperative problem. The users＂ interference and the S1NR error are considered to give a new Cost function,because the non-cooperative game is unfair for the far users and the slow traditional algorithm convergence. What＇s more, use the new cost function to the rate control, and the existence and uniqueness of the proposed algorithm＇s NASH equilibrium are proved. The simulation results show that the algorithm can attain higher transmission rate using lower power and better convergence rate. The fair of the system for the far users is also illustrated in the proposed algorithm
