噪声中复指数载波信号的频率估计是信号处理中的一个关键问题。为了解决这个问题,本文提出了一种新的迭代频率估计器。通过迭代计算DTFT样本的内插,该算法获得了较好的频率估计。此外,本文还对其均方误差进行了分析。通过分析可选参数对模型估计精度的影响,讨论了选择合适参数的方法,有助于减小所提出的估计器的估计误差。仿真结果表明,与其他估计精度相当的算法相比,所提出的迭代估计器可以获得更接近Cramér-Rao下界的均方根误差(RMSE)。
The frequency estimation of complex exponential carrier signals in noise is a critical problem in signal processing. To solve this problem, a new iterative frequency estimator is presented in this paper. By iteratively computing the interpolation of DTFT samples, the proposed algorithm obtains a fine frequency estimate. In addition, its mean square error (MSE) analysis is presented in this paper. By analyzing influences of the selectable parameters on the estimation accuracy of the model, a method for choosing appropriate parameters is discussed, helping to reduce the estimation error of the proposed estimator. Simulation results show that compared with other algorithms with a comparable estimation accuracy, the proposed iterative estimator can obtain a root mean square error (RMSE) that is closer to Cramér–Rao lower bound (CRLB).
