There are two main alternatives, Direct Sequence Spread Spectrum and Frequency Hopping Spread Spectrum(FHSS). 重要有两种选择,直接序列扩频和跳频扩频(FHSS)。
The frequency hopping spread spectrum systems in the generator of jamming signal by programming is introduced. 文中介绍了扩频跳频技术在干扰信号产生中的应用。
Frequency hopping spread spectrum communication is a hot topic of international research. 跳频扩频(FHSS)通信是目前国际上研究的热点课题。
And based on these, the paper proposes an effective method for the detection of correlated frequency hopping spread spectrum signals : the correlation analysis method based on delay multiplication low-pass filtering. 提出了一种可实现对相关跳频扩谱信号侦察检测的有效方法&基于延迟相乘低通滤波的相关分析法。
This paper presents two transform domain approaches to suppress the narrowband interference in a hybrid direct sequence frequency hopping spread spectrum system. 分别给出了DS/FH混合扩频系统中窄带干扰的两种变换域处理方法。
