摘　　要：扩频通信系统中的载波同步是指收发两端的载波都应步调一致地进行工作,不仅要求同频,而且对相位也有严格的要求。本文对扩频通信系统中的载波恢复进行了仿真研究,得到了系统主要输出点波形,同时对系统在高斯白噪声情况下的误码性能进行了分析。The carrier synchronization in spread spectrum system means the carriers in both transmitting and receiving ends should operate in unison, not only same frequency is required, but also the phase is strictly required. In this paper simulation study on the carrier recovery in spread spectrum communication system is carried out, obtaining the waveforms of main output points, in the same time the system BER in the case of Gauss white noise is analyzed.
