摘　　要：基于子带分解的自适应滤波器在提高收敛性能的同时又可以节省一定的计算量。采用Altera公司的仿真软件Altera DSP Builder和QuartusⅡ7.2进行子带分解的NLMS算法的自适应滤波器现场可编程门阵列设计,利用Si mulink和ModelSi m对设计方案进行了模型仿真和功能仿真,达到较好的效果。The self-adaptive filter based on subband decomposition can improve convergence speed and save computation. The field programmable gate array （FPGA） design of the self-adaptive filter based on subband decomposition NLMS algorithm is accomplishedwith the simulation softwares Altera DSP Builder and QUARTUS Ⅱ7.2. The design scheme was demonstrated with Simulink for model simulation and the ModelSim for function simulation. A good result was achieved.
