摘要

本文提出了一种基于最小均方(LMS)算法的自适应噪声消除器的FPGA实现。硬件架构以Xilinx Spartan-3e Starter Kit为目标板进行综合。硬件实现的实验结果表明了LMS算法在不同条件下的性能和架构的可行性。然后用不同的滤波器抽头对硬件和纯软件实现进行比较。

FPGA Implementation of an Adaptive Noise Canceller
This paper proposes an FPGA implementation of an Adaptive Noise Canceller using the Least Mean Square (LMS) algorithm. The hardware architecture is synthesized using the Xilinx Spartan-3e Starter Kit as the target board. The experimental result of the hardware implementation shows the performance of LMS algorithm under different conditions and the feasibility of our architecture. A comparison between hardware and pure software implementation is then made with different filter taps.
