捕获是扩频通信系统的关键技术之一，本文针对ＩＳ－９５码分多址蜂窝通信系统标准，给出了一种适合于上行信道接收机的捕获方案，分析了虚警概率和检测概率，并介绍了该方案的ＦＰ－ＧＡ实现。该方案简单可行，采用并行结构，具有捕获时间短，硬件资源消耗少的特点。
Acquisition is one of the key technologies of spread spectrum communication system. In this paper, aiming at the standard of IS-95 code division multiple access cellular communication system, an acquisition scheme suitable for uplink channel receiver is given. The false alarm probability and detection probability are analyzed. And introduces the FP-GA implementation of the program. The scheme is simple and feasible, adopts the parallel structure, has the characteristics of short acquisition time and less hardware resource consumption.
