摘要
通过对智能天线LMS算法的分析和研究,发现了传统的LMS算法存在收敛速度和稳态误差之间无法兼顾的问题,即固定步长因子无法解决收敛速度和稳态误差之间的矛盾。提出了一种改进的LMS算法,并通过计算机仿真对该算法进行了验证。改进的LMS算法的应用有效地解决了LMS在收敛方面存在的问题。
By analyzing and researching the LMS algorithm of smart antenna, it is found that the traditional LMS algorithm can not solve the problem of the convergence rate and the steady-state error at the same time, that is. the permanent step factor can not solve the contradiction between the convergence rate and the steady-state error. So an improved LMS algorithm was proposed and verified by computer simulation. The application of the improved LMS algorithm efficiently solves the problem in a convergent process.
