摘要

本文研究非高斯ＡＲＭＡ有色噪声中的正弦信号频率估计问题。利用自相关函数和三阶累积量相结合，提出了一种先估计噪声模型ＡＲ参数，然后对观测值进行预滤波，最后估计信号模型参数的新方法，模拟实验结果表明，新方法具有良好的频率估计性能。

Abstract

This paper discusses the problem of estimating the frequencies of sinusoidal signals in colored non-Gaussian ARMA noise.Combining third-order cumulants with autocorrelations

we propose a new method in which AR parameters of noise model are first estimated ;then the measurement sequence is prefiltered ;finally

the parameters of signal medel are estimated. Simulation examples are presented to demonstrate the well frequency estimation performance of this method.
