针对色噪声背景下的二维谐波频率估计问题,本文提出了拓广的二维ESPRIT算法.该算法对二维MA模型的噪声具有比较好的抑制能力.同时,对于二维频率配对问题,本文给出了一种更为简便的方法.仿真实验验证了算法的正确性.

An extended ESPRIT type method was presented to extract frequencies from the signal which was contaminated by two-dimensional colored Gaussian noise.If the noise has the characteristic of MA model,this method can restrain it effectively.In addition,a new pairing method was also presented.Theory and algorithm are illustrated by simulation examples.
