基于DSP的自适应FIR滤波器设计与实现

摘要

The article introduces the design and implementation of the adaptive FIR filter based on DSP.TMS320VC5402 DSP chip is used as the center processor to design and implement the adaptive FIR filter.The hardware system design module,the software system design flow chart and the related assembly code are given.The results of simulation and measurement show that the designed filter can perfectly eliminate the noise which disturbs the input signal.%介绍了基于 TMS320VC5402 DSP 的自适应 FIR 滤波器的设计与实现。采用TMS320VC5402 DSP芯片作为处理单元，设计并实现了自适应FIR滤波器，给出了硬件系统设计模块，软件系统设计流程图及相应的汇编代码。仿真结果和实现结果表明所设计的自适应FIR滤波器能很好的消除叠加在信号上的噪声。
