摘要
伪随机码在扩频通信中得到广泛应用。目前的卫星导航定位系统大多采用扩频通信技术来传输导航信息 ,常用的伪随机码是平衡Gold码。对平衡Gold码的特性和产生方法作了研究 ,对全球定位系统 (GPS)粗码的平衡性作了分析 ,最后给出了在SystemView平台上相应的仿真结果。
The pseudo random noise ranging code has been applied extensively to spread spectrum communications.Currently most satellite navigation systems utilize the spread spectrum communication technology to transmit navigation information,and the commonly-used PRN ranging code is the balanced Gold code.In this paper,the characteristics and producing approach of the balanced Gold code are studied,and the balance of the coarse/acquisition code of GPS(global positioning system)is analyzed.Finally the results of the corresponding simulation on the platform of System View are presented.This study can be used for reference in the related work.
