| 摘 要： | 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。

| Abstract: | In this paper, firstly, we introduce a decoupled parameter estimation (DPE) algorithm for the parameter estimation of the sinusoidal signal, then we present an iterative clean algorithm to obtain the estimates of the parameters of the multi-period signal in colored noise based on FFT. This algorithm not only is computationally simple but also can provide superresolution frequency estimation. Simulation results by the numerical data show the efficiency of this algorithm. |
