- 摘要:
- 针对传统方式开发的自适应滤波器效率低、难度大的缺点，利用DSP Builder，设计出了基于延时最小均方(DLMS)算法的16阶系统辨识自适应滤波器。仿真与测试表明了设计的正确性，并在Cyclone Ⅱ系列FPGA芯片上完成了硬件验证，滤波器最高频率达到82.07 MHz，数据吞吐量显著提高。
- Abstract:
- Traditional ways of developing adaptive FIR filter have the disadvantages of low efficiency and much difficulty.A model of 16-taps adaptive FIR filter based on the DLMS algorithms was designed based on the DSP Builder.The simulation and test results verified the correctness of the design.The FPGA implementation of the filter was based on the Cyclone Ⅱ series.The top frequency of the filter achieved 82.07 MHz,which indicated that the throughput of DLMS was more higher than usual ones.
