| Abstract: | On the basis of CPM,this paper presents a method of using the correlator to assist the realiza- tion of synchronization,which falls into two kinds:difference correlation method and absolute phasic correla- tion method.By MATLAB simulation,the performance of the two methods is analyzed.On the basis of per- formance optimization,a simplified algorithm realized by FPGA is proposed,which saves the logic resource of FPAG and makes the realization of the correlator possible. |
