| Abstract: | The technology of carrier synchronization recovery is a key technology in correlation demodulation. Base on summarizing the common methods. A new method of carrier synchronization recovery is put forward in this paper.This method has the merits such as high efficiency, high precision, building synchronization quickly and keeping synchronization long. And it is validated by MATLAB, the result indicates the theoretics is right and the method is doable. |
