随着传播终端的发展，它们的设计更倾向于基于软件的方法，便于方便地调整和定制接收器算法。一种潜在的改进是实现频率估计算法，通过该算法，可以以比简单的FFT频谱峰值搜索高得多的分辨率来估计接收信号的主频率分量。为了选择在Q/V频段信标接收机中使用的估计器，对六个频率估计器进行了分析，以表征它们与信标接收机设计相关的有效性。
As propagation terminals have evolved, their design has trended more toward a software-based approach that facilitates convenient adjustment and customization of the receiver algorithms. One potential improvement is the implementation of a frequency estimation algorithm, through which the primary frequency component of the received signal can be estimated with a much greater resolution than with a simple peak search of the FFT spectrum. To select an estimator for usage in a Q/V-band beacon receiver, analysis of six frequency estimators was conducted to characterize their effectiveness as they relate to beacon receiver design.
