摘　　要：在简述发射QPSK波形的必要性与可行性的基础上,阐述了所需发射的波形及其捕获方法,重点对基于载波频率快速傅里叶变换（fastFourier transform,FFT）的方法进行了分析与改进,并通过Matlab对改进后的方法进行仿真,仿真结果验证了该方法的可行性。The importance of synchronization for DSSS system was firstly discussed,then the QPSK waveform to be transmitted and the species of acquisition methods were expatiated respectively.The fast Fourier transform（FFT）method based on carrier frequency is analyzed and improved stressly and simulated by Matlab,and the results of simulation indicate that the method is feasible.
