摘要
本文以现代谱估计为基础,为估计淹没在噪声中的正弦波的频率,介绍了常用的四种频率估计技术,即最大似然法、修正协方差法、特征向量法、多信号分类法。以实际过程为例证,对这四种方法进行了原理介绍、仿真实现和结果分析。
In order to estimate the frequency of sine wave submerged in noise, this paper introduces four kinds of frequency estimation techniques, which are based on modem spectrum estimation, namely maximum likelihood method, modified covariance method, eigenvector method and multiple signal classification method. By the example of substantial random process, this paper clearly deals with principle introduction, emulation realization and result analysis of the four methods.
