利用游程统计的办法估计长码参数

Estimating Long Code Parameters by a Statistical Way

摘要:在现阶段,长码在GPS,CDMA通信等领域发挥着很重要的作用,因此也是信息对抗研究的重点对象。利用长码中固有的统计规律来估计长码的寄存器长度,抽头多项式等参数,从而在只接收部分长码的情况下计算出整个长码周期。

Nowadays, long code plays a very important role in GPS, CDMA and many other fields, which makes it to be an important study subject in electronic counter measures. A new statistical way is introduced in this article to estimate the long code parameters, which only needs to know part of the long code.
