| Abstract: | Based on study of LMS algorithm, a new algorithm named ELMS algorithm is proposed in this paper, which is adapted for an ANC (Adaptive Noise Cancellation) system. The comparison of the statistical performance between ELMS and LMS algorithms is analyzed. Based on the conjugate method of an optimum theory, a new MVS ANELMS algorithm is also proposed. By the computer simulation, it can be concluded that the new algorithms are better than the LMS with a little added computation. |
