摘要
直接序列扩频技术以其优良的抗多径干扰、安全性和测量时间的精确性成为陆地无线测控网中关键技术之一。本文主要介绍在ITURAN测控网定位系统中上行定位链路中的直接序列扩频技术,并采用MATLAB对其性能进行了仿真试验,仿真的结果证明了直接序列扩频技术具有较强的抗多径干扰能力。
The direct sequence spread spectrum technology （DSSS）as its anti-multipath interference, security and accuracy of measurement of time is one of the essential technologies in terrestrial wireless monitoring and control network. The DSSS used by location Up-Link of ITURAN terrestrial wireless monitoring and control network system will be presented in this paper. The simulation of DSSS will be taken by using MATLAB, and the simulation results proved that direct sequence spread spectrum technology has strong anti-multipath interference ability.
