首先介绍了一种估计有色噪声中多个正弦信号参数的去耦参数估计算法，然后提出了一种基于ＦＦＴ的“迭代清除算法”来估计有色噪声中多个周期相近信号的参数。该算法不仅计算简单，而且可获得较高的频率分辨率。数值仿真结果表明了该算法的有效性。
Firstly, a decoupling parameter estimation algorithm for estimating multiple sinusoidal signal parameters in colored noise is introduced. Then an FFT-based iterative elimination algorithm is proposed to estimate the parameters of multiple periodic similar signals in colored noise. The algorithm is not only simple to calculate, but also can obtain higher frequency resolution. Numerical simulation results show the effectiveness of the algorithm.
