摘要
为了提高捕获算法性能和减小各通道间信号互扰,提出了一种新的捕获算法.在接收端采用线性内插的信号恢复方法进行多通道信号检测,利用检测到的信号消除通道间信号互扰.为了改善捕获性能,对门限检测进行了改进仿真,结果表明,当各通道信号功率相当或者一通道信号功率明显大于其他信号时,该算法均可有效提高捕获性能.
A new acquisition algorithm is proposed to improve the acquisition performance and reduce multi-access interference. Linear interpolation is used to replicate the original signal. Threshold detection algorithm is improved for better acquisition performance. Simulation experiment results showed that the new algorithm effectively improves the acquisition performance.
