-
摘要: 该文提出了一种用于CDMA网络规划的的上行功率迭代算法。在迭代的过程中，移动台根据各个基站的负载情况，动态地选择所连接的基站，使发射功率最小，最终使移动台的发射功率和基站处的干扰功率收敛。对算法的收敛性给出了理论分析，仿真结果验证了理论分析的正确性。该算法便于计算机实现，可用于实际的网络规划。

Abstract: An uplink power iterative algorithm is proposed for CDMA network planning. In the iteration, the mobile station is dynamically assigned to the home station which can minimize the mobile station transmitted power according to the load of the base stations. So the transmitted power of the mobile station and the received power of the base station is converged. The convergence of the algorithm is analyzed in therotical, and simulation results demonstrate the correctness of theoretical analysis. The presented algorithm can be implemented easily by computer. Thus it can be used for practical network planning. -
