摘要: 本文提出一种自适应消除干扰的新算法(使用矩阵的奇异值分解SVD定理).该算法先 由参考输入的自相关函数及参考输入与主输入之间的互相关函数,估计出自适应滤波器的脉 冲响应,然后由矩阵的奇异值分解定理计算滤波器的系数.文中并给出计算滤波器脉冲响应 的一种递推算法.在数字计算机上的仿真结果说明了该算法的特性.Abstract: A new algorithm for noise cacellation using singular value decomposition of matrix is presented in this paper. By this algorithm, the impulse response of an adaptive filter from an auto-correlation function and cross-correlation function of reference input and primary input is first estimated, and then using singular value decomposition of matrix, the coefficients of the filter is obtained. A recursive algorithm for calculating the impulse response of the adaptive filter is also presented. Simulation results illustrate the behavior of the algorithm.
