作者研究了一种适用于多频信号参数实时估计的频域程序中加窗对精度的影响。对噪声的统计描述施加非常弱的假设，建立了简单而准确的估计量方差表达式。它们既可以评估结果的准确性，也可以设计测量程序。仿真结果验证了分析的有效性。>
The author investigates the influence of windowing on the accuracy of a frequency-domain procedure suitable for real-time estimations of multifrequency signal parameters. Imposing very weak assumptions about the statistical description of the noise, simple and accurate expressions for the estimator variances are established. They allow both the evaluation of the result accuracy and the design of the measurement procedure. Simulation results confirm the validity of the presented analysis. >
