摘要
扩频码的捕获是扩频通信的前提。无论哪种捕获方式 ,检测门限是一个基本参数。提出了一种基于功率估计的门限调整技术。接收信号信噪比在一定范围内变化时 ,可以自适应地调整检测门限。
Capturing spread spectrum sequence is the premise of spread spectrum communication. But detection threshold is a basic parameter no matter which capturing way is used. This paper proposes threshold adjusting technology based on estimation of power. When the SNR of received signal varies in certain range, the technology can adjust detection threshold adaptively. Finally computer simulations are presented.
