摘要

本文提出了一种基于迭代算法的八通道滤波器组单频正弦信号频率估计方法

该算法的基本思想是利用频域重叠的多通道滤波器来实现大的频率估计范围

同时提高单通道内的信噪比;还对滤波抽取后的数据进行迭代

这样即使采用运算量最小的不加权线性预测算法也能实现高精度测频

并采用FPGA实现了该算法

最后数值仿真结果证实所提算法的优异性能.

Abstract

A novel iterative algorithm base d on eight channel filter bank to estimate single-frequency is proposed.A highly overlapped filter bank is adopted in the proposed method to extend frequency estimation arrange and increasing SNR in single channel.By exploiting filter and decimation

the iterative algorithm is applied.Through this way the computational complexity is kept low and estimation is accurate

even adopting the simplest estimation method

Un-Weighted Linear Predictor (UWLP).Furthermore this frequency estimator has been realized by FPGA.The computer simulation result shows the proposed method has good performance.
