Modeling and Simulation Analysis of Carrier-Suppressed Differential Phase Modulation Signals in Optical Communication

This paper introduces a novel methodology for modeling and simulation analysis of carrier-suppressed differential phase modulation signals in optical communication systems. The proposed approach enables comprehensive investigation of signal characteristics and performance metrics through numerical simulation. Key implementation aspects include differential phase encoding algorithms (e.g., using modulo-2π arithmetic), carrier suppression techniques via balanced modulation schemes, and BER performance evaluation through Monte Carlo simulations. The modeling framework incorporates optical field equations and demodulation processes, allowing thorough analysis of signal transmission and recovery mechanisms. System optimization parameters include phase deviation settings, sampling rate configurations, and noise tolerance thresholds. Furthermore, we discuss practical applications in coherent optical systems and identify future research directions for enhancing spectral efficiency and transmission robustness through adaptive phase recovery algorithms and machine learning-based signal processing techniques.
