摘要
本文讨论高斯有色噪声中的正弦信号参量估计问题。利用观测值的高阶统计量信息，建立了四阶累积量ＥＳＰＲＩＴ方法。模拟实验结果表明，该方法不仅具有很高的频率分辨率，而且能抑制高斯有色噪声的影响。
This paper discusses the problem of estimating the parameters of sinusoidal signals in colored Gaussian noises. Fourth-order cumulant-based ESPRIT approach is suggested which uses higher-order statistics of measurements. It is demonstrated by simulations that the new approach has high resolution and can suppress the effect of colored Gaussian noises.
