摘　　要：为了在扩频通信中实现伪码的快速捕获,通过对相关积分包络算法的改进,对接收信号未知伪码进行相位搜索,完成了FPGA仿真验证,实现的伪码捕获具有结果误差小、捕获时间短、占用资源少等特点。In order to realize the quick pseudo code capture in spread spectrum communication, the correlative integral enveloping algorithms was improved. The phase search for the unknown pseudo-code in the received signal is performed with the algorithm. The simulation verification of FPGA was completed. The pseudo-code capture method has the following characteristics： small error, short capturing time, less resource occupation.
