摘要
频率估计是信息科学在信号处理领域的一个重要组成部分,在许多实际信号处理应用中具有非常重要的地位,且已广泛应用于雷达、地震、生物医学、语音处理和故障诊断等领域。文中归纳了频率估计的分析方法,并对主要的频率估计方法进行介绍和评述,最后对频率估计的发展方向进行了展望。
Frequency estimation is an important component in the field of signal prosessing,it has a very important position in the application of signals processing, and it has been widely applied in radar, seismic signal processing, biomedical speech processing , fault diagnosis and many other fields. The methods of frequency estimation are summaried in this paper, and the main methods are discussed and compared. In the end, the methods of frequency estimation are prospected.
