【摘要】 自适应滤波器为一个未知系统的建模提供了一种简单,实用的方法。可以在不知道系统的理论模型的条件下,通过测量和学习,实现对未知系统的最佳拟和。本文简要介绍了自适应滤波在信号处理系统建模中的应用,着重讨论了ⅡR递推结构自适应滤波器的LMS算法。在此理论基础上用matlab语言实现了对一个数字音效处理系统的建模。最后,简要介绍了该数字音效系统的DSP系统实现。更多还原

【Abstract】 Adaptive filter provides a kind of simple and applied method for the modeling of an unknown system. It can attain a best approach of the unknown system through measuring and learning, on the condition that the theoretical model of the system is unknown. This paper makes a brief discussion on the application of adaptive filters in the simulation and recognition of signal processing systems, particully on the LMS algorithm of IIR adaptive filter. Then, modeling of a digital audio effect processing system is implemented in matlab language based on the theories mentioned above. In the end, the hardware implementation of this system is given.更多还原
