Abstract

The variable step LMS algorithm can construct appropriate factor and adjust its filter parameters to achieve the optimal filter. But for the blind signals whose frequency bandwidth is different largely, the traditional variable step LMS algorithm can't meet the requirements. To design a new effective filtering algorithm, a correction function is introduced. It greatly improves the convergence speed of the algorithm, when the error is relatively large. The principle of the new algorithm is illustrated, and the simulation results show that the new algorithm is very effective. In the end, the new algorithm is applied in blind satellite signals frequency domain filtering, and good results are achieved.
