摘要:归一化LMS(NLMS)算法是一种变步长的LMS算法,比LMS算法具有更快的收敛速度.采用Altera 公司的仿真软件DSP Builder和QUARTUSII7.2,进行归一化LMS算法的自适应滤波器的现场可编程门阵列(FPGA)设计.

关键词: NLMS算法, DSP Builder, 自适应滤波器, FPGA

Abstract: The convergence rate of the Normalized Least-Mean-Square(NLMS) algorithm with variable step length  is higher than that of the Least-Mean-Square algorithm,and the Field Programmable Gate Array (FPGA)design of the adaptive filter using Altera DSP Builder and QUARTUS II 7.2 is accomplished.

Key words: NLMS algorithm, DSP Builder, adaptive filter, FPGA
