摘要

本文提出了一种基于简单相位误差准则（PEC）的自适应算法，用于在加性白高斯噪声和脉冲噪声中估计复正弦信号的频率。该技术利用一阶复数线性预测器（CLP）的瞬时相位响应作为驱动函数来更新 CLP 的频率参数。拟议的 PEC 因其简单性和高脉冲噪声鲁棒性而极具吸引力。理论分析得出了频率估计值的平均值和稳态均方误差（MSE）的闭合形式。计算机模拟显示了拟议频率估计器的性能。

Phase Error Criterion Based Adaptive Algorithm for Frequency Estimation

A simple phase error criterion (PEC-)-based adaptive algorithm for estimating the frequency of a complex sinusoidal signal in additive white Gaussian and impulsive noises is proposed. The proposed technique makes use of the instantaneous phase response of a first-order complex linear predictor (CLP) as a driving function to update the frequency parameter of the CLP. The proposed PEC is attractive due to its simplicity and high impulsive noise robustness. Theoretical analysis for the mean value of the estimated frequency and the steady-state mean square error (MSE) of the frequency estimate are derived in closed forms. Computer simulations are drawn to show the performance of the proposed frequency estimator.
