BER Calculation for Co-Simulation with Optisystem

This document describes the methodology for implementing Bit Error Rate (BER) calculation through co-simulation between MATLAB and Optisystem. The program enables engineers to effectively evaluate communication system performance and identify debugging directions. The implementation employs cross-platform data exchange mechanisms where Optisystem handles optical signal transmission simulation while MATLAB processes digital signal analysis. Key functions include automated signal synchronization, threshold detection algorithms, and statistical error counting modules. Usage involves three streamlined steps: first, import the interface scripts into both MATLAB and Optisystem environments; second, configure system parameters through the unified control panel (supports preset optical power levels, modulation formats, and noise models); finally, execute the co-simulation routine to generate comprehensive BER versus signal-to-noise ratio curves. Testing validates the program's reliability in performing Monte Carlo simulations with error correction coding integration, significantly simplifying communication system debugging processes.
