In the condition of long pseudo code and large carrier Doppler frequency shift, the number of FFT points in the conventional synchronous acquisition algorithm is too large, the complex multiplication is of high computational complexity and large time cost, and the parameter evaluation acquired in a long duration is not applicable for carrier tracking because it is too old.

当伪码较长、载波多普勒频移较大时，传统的同步捕获算法进行的FIT点数较多，复数来加运算量大，耗时长，而在校长的捕获时间内，捕获得到的参数估计过于陈旧，无法应用于载波跟踪，为此，文中提出了一种改进的快速同步方法。
