ARMA噪声中的正弦波检测

本文提出一种ＡＲＭＡ噪声中正弦波检测的方法，本方法先用改进的Ｐｒｏｎｙ法估计可能存在的正弦波，然后利用一种综合考虑衰减因子以及ＭＵＳＩＣ值的准则从估计结果中区分正统率波的真伪。数值例子表明，本文方法比Ｐｒｏｎｇ方法及ＭＵＳＩＣ方法具有更高的分辨力。

Resolving Sinusoids in ARMA Noise

This paper proposes an approach to resolving sinusoids in ARMA noise. In this approach, several possible sinusoids are first estimated by using an improved Prony method developed in this paper, and then a criterion combining damping factors and MUSIC values is used to discriminate between true and pseudo sinusoids. Numerical examples show that this paper's approach is of high resolution.
