为了解决采用 LMS 算法进行波束形成时收敛速度与稳态误差不能同时满足的缺点,提出一种改进的最小均方算法,它使用统计平均进行梯度更新解决瞬时梯度导致的形成波束不稳定问题,旨在波束形成开始阶段加快速度,而在收敛达到稳定状态后保持小的误差值。 |
In order to solve the shortcoming that the convergence rate and steady-state error can not be satisfied simultaneously when using the LMS algorithm, an improved least mean square algorithm was proposed, which used the statistical average gradient update to solve the problem of the formation of beam instability caused by the instantaneous gradient, which can speed up at the beginning of the beam-forming and maintain a small error value after the convergence has reached a steady state. |
