Carrier Synchronization Simulation Design Based on MATLAB/Simulink

Carrier synchronization is an important link in wireless communication systems. It ensures frequency and phase synchronization between the receiving end and the transmitting end, thereby achieving reliable data transmission. The accuracy of carrier synchronization is crucial to ensure the performance of communication systems, especially in the case of high-speed data transmission and multi-user access. This article first investigates the current mainstream carrier synchronization algorithm, analyzes its working principle, and analyzes the characteristics of its mathematical model. By comparing the mainstream synchronous carrier implementation methods, two of them were selected, and the simulation models of square ring and COSTAS ring carrier synchronization were built using MATLAB/Simulink simulation software and its code program. Simulink simulation showed that it can be well realized. Simulation design of square ring and COSTAS ring carrier synchronization, and analyzed and compared the impact of square ring and Costas ring carrier synchronization methods on the coherent demodulation effect. The feasibility of the two carrier synchronization technologies has been verified through simulation, and both can better coherently demodulate the signal and have a high degree of signal restoration.
