摘要
针对无线电测距对扩频码的特殊要求,通过对传统的扩频码的比较分析,提出在无线电导航系统中引入移位序列作为扩频地址码。并对其相关特性进行仿真,通过仿真可知,它改进了测距扩频码 m 序列的互相关特性和 Gold 序列的自相关特性,从而提高了系统的性能,成为无线电导航系统扩频码的最优选择。
To satisfy the unique request of PN sequences optimization,the paper proposes a scheme in which a set of shift sequences of one m-sequence are used as SS code in radio navigating system.We learn it will improve the cross- correlation of m-sequences,auto-correlation of Gold sequences through simulation,and then the performance of sys- tem.So it is the best one for radio navigating system.
