自适应滤波器LMS算法的DSP实现

Realization of Adaptive Filter LMS Algorithm by DSP

滤波器在数字信号处理中有着广泛的应用,针对常规滤波器因具有固定的滤波器系数,对某些信号处理系统不能实现最优滤波,设计了一种自适应滤波器及实现的软件算法,并通过DSP得到验证。结果表明该滤波器实现方法简单、不依赖模型,具有较强的稳健性。

Filter is widely used in digital signal processing. For the conventional filter has a fixed filter coefficients,optimal filtering can not be achieved in some glgnal processing system. The design and the software algorithms of the adaptive filter is realized. The filter has been tested and adopted in DSP. Experiments show that the realization method of the filter is simple. This filter doesn＇t rely on model, and has strong stability.
