设计自适应滤波要求使用DSP实现自适应滤波器，要求掌握自适应滤波器的原理和实现方法。因为自适应滤波器的设计用到了自适应算法和FIR滤波算法-Design of adaptive filter requires the use of DSP implementation of the adaptive filter, requirements and implementation methods of master the principles of adaptive filter. Because the design of adaptive filter used in the adaptive algorithm and FIR filter algorithm
