| 摘 要： | 传统的基于声光技术的信号处理模型被建模为平稳随机过程,而在扩频通信中,信号是被伪码调制的循环(周期)平稳信号。因此,扩频信号应被建模为循环平稳随机过程。基于声光信号处理技术和循环平稳随机过程理论,建立了声光循环平稳信号处理模型,并应用于扩频通信中,理论分析和仿真表明,声光循环平稳信号处理技术在扩频通信领域的信号分析中是十分有用的。

| Abstract: | The signal is assumed to be stationary in the conventional acousto-optic(AO)signal processing,but the spread spectrum(SS) signal is modulated by pseudo noise code and belongs to typically periodic signal,accordingly,should be the cyclostationary(CS)signal.Based on the AO signal processing technology and CS theory,the model of AO CS signal processing was presented,and used to analyze the SS signal.The simulations show that the AO CS signal processing technology is powerful analysis tool in SS communication. |
