Abstract

At This Stage, China's Science and Technology Continue to Develop, Optical Fiber Technology Continues to Improve, and the Loss is Gradually Reduced, Which is Widely Used in Communications. At Present, Optical Fiber Communication Has Basically Been Popularized. However, the Application of Multi-Level Phase Shift Keying Coherent Optical Communication System Still Has Some Problems, and It is Difficult to Meet the Actual Production and Living Needs. Based on This, This Paper Elaborates on the Relevant Theory and Analyzes the Carrier Phase Estimation. Finally, a Multi-Level Phase Shift Keying Coherent Optical Communication System is Built and Digital Adaptive Carrier Phase Recovery Simulation is Carried out.
