| 摘 要： | 互谱估计方法是用于色声背景正弦参量估计的一个非常有效的方法。互ＥＳＰＲＩＴ法除克服了互ＭＵＳＩＣ法所需的谱峰搜索所带来的计算量非常大之外，也消除了采用自相关函数的ＥＳＰＲＩＴ法本身所含方差大的缺点。是一种较理想的谱估计方法。

| Abstract: | The Cross spectral estimation methods are efficent in estimating the parameters of simusoidal signals embeded in colored noisc.Cross ESPRIT methods can estimate the parameters without large calculation of Cross MUSIC methods researching spectral peak.On the other hand,it eliminstes the mean square error of the Autocorrelation function ESPRIT.It is a better estimation method. |
