| Abstract: | This paper introduces several methods to acquire the carrier wave of the unified system, and provides an efficient method to realize the acquisition of carrier wave of unified system. To confirm the validity of this method, an example is provided to compare the operation time of several methods, and to verify the efficiency of the method. |
