摘　　要：周期平稳信号是一类非常重要的非平稳信号,许多信号、干扰都表现出一定的周期平稳性,将信号的这种特性考虑在内的信号处理器,较之传统的信号处理器,可以得到性能上的提高。本文对周期平稳信号处理的基本理论和方法,以及它在各领域中的应用作一概要总结,并在此基础上,对周期平稳信号处理新的发展和应用方向予以展望。Cyclostationary signal is an important class of non-statinary signal. Many signals and/or inteferences show certain degree of cyclostatioinarity. Therefore, signal processors considering this property of the signal can obtain many performance advantages over conventional signal processors. This paper first reviews some fundamental conceptions and methods of cyclostation-ary signal processing theory, followed by a comparatively thorough summary of its applications. Finally, directions of future development and application are dicussed.
