摘要
本文中的算法是交织了一个固定点功率控制算法,该算法是利用以多用户检测MMSE为标准的Aitken’s过程加速的。通过应用于MMSE滤波器的扩展Steffensen算法,得自关于Lip-shitz常量的一个下限。Lipshitz常量是用来保证所提算法的收敛性。此算法体现了渐进二次收敛,是以牛顿方法为基准。最后给出了仿真结果。
The proposed algorithm interweaves a fixed point power control algorithm accelerated by utilizing Aitken＇s process with MMSE multiuser detection. By using extended steffensen algorithm applied to MMSE filter, the paper further evaluated a lower bound on the Lipshitz constant which can be used to ensure convergence of the proposed algorithm. The algorithm shows asymptotically quadratic convergence and is benchmarked against Newton＇s method. At last, the simulation results are given.
