摘要

代码捕获时间的概率分布给出了代码捕获时间的完整描述。分析了直接序列扩频接收机的串行搜索多驻留码采集，并利用其矩生成函数推导了采集时间概率分布。该方法应用于非选择性衰落信道，该信道导致接收信号的幅值随机变化。概率分布表示为给定振幅概率分布的平均值。

On DS-SS code acquisition time probability distribution-Serial search by multiple-dwell detector in fading channel

The complete description of code acquisition time is given by its probability distribution. In the contribution, serial search multiple-dwell code acquisition of a direct sequence spread spectrum receiver is analyzed and acquisition time probability distribution is derived using its moment generating function. The method is applied to a nonselective fading channel, which causes the amplitude of a random received signal. The probability distribution is expressed as an average over a given amplitude probability distribution.
