扩展频谱(以下简称“扩频”)通信在现代通信中是一种很重要的技术,具有抗干扰性强和保密性好的能力;在测距中可以改善测距精度,因为测距精度与扩展带宽有关;利用具有相同谱的码分多址,多个用户可以共用一个信道。 SAW器件在通信系统中有很多应用。本文主要是介绍SAW-MSK信号调制器/产生器和SAW卷积器在扩频通信系统中的应用并报道某些实验结果。
Spread spectrum (hereinafter referred to as “Spread Spectrum”) communication is a very important technique in modern communication and has strong anti-interference ability and good confidentiality; Ranging accuracy can be improved in ranging, ranging accuracy and Extended bandwidth; using the same spectrum code division multiple access, multiple users can share a channel. SAW devices have many applications in communication systems. This paper mainly introduces the application of SAW-MSK signal modulator / generator and SAW convolver in spread spectrum communication system and reports some experimental results.
