查询词典 DS

Theoretical and simulating results show that DS/SS signal can be demodulated efficiently by using this method.

研究了混沌二相码序列在雷达波形设计中的应用。

The communication technology used in GPS is a direct sequence spread spectrum structure. Using C/A Gold codes, it can cope with wideband noise (such as thermal noise and channel noise) or low power narrowband interference by its processing gain. But DS-SS can not reject high power narrowband interference completely. So we need an anti-jamming filter to reject the narrowband interference by using adaptive filters prior to dispreading.

它是利用直接展频的一种架构，因此，此系统能藉由C/A码的展频处理增益，来对付ㄧ些宽频的干扰或是低能量的窄频干扰，但是它无法应付高能量的窄频干扰，因此我们需要一个抗干扰滤波器在解展频之前来先将干扰去除。

Radio resource can be effectively managed and the transmission information is difficult to be detected and eavesdropped by others.

因此，本文主要针对DS-CDMA移动多用户通信系统，研究改善其系统性能的技术问题。
