摘要
为了解决快速提取直接序列扩频通信信号伪码码速率的难题,详细介绍了一种用延时相乘法实现快速提取直扩信号伪码速率的原理和实现方法。理论分析和计算机模拟表明,该方法在较低的输入信噪比条件下具有较高的识别率。
In order to solve a difficult problem on fast detection and recognition to the PN code rate of DS/SS Signal, a method which is based on delay-and-multiplication is analyzed in detail. The results of computer simulation show that this method can recognize PN code rate exactly on the low ratio input signals.
