MFSK Modulation and Demodulation System in Rayleigh Channel using Simulink

This Simulink-based MFSK modulation and demodulation system operating in Rayleigh fading channels uses 8FSK as a primary example, with architecture designed for easy expansion to other MFSK configurations. The system implementation includes comprehensive analysis modules for spectrum diagrams (using FFT-based spectral analysis blocks), eye patterns (via sampling scope components), and constellation diagrams (utilizing scatter plot functions). The demodulation performance is evaluated through BER calculation algorithms incorporating error rate computation blocks and statistical analysis tools. Furthermore, the system allows for in-depth investigation of Rayleigh channel effects on performance metrics, including techniques for system optimization through parameter tuning of channel characteristics and modulation schemes. Additional research directions include comparative analysis of different modulation techniques using parallel simulation frameworks, along with practical performance validation methods employing Monte Carlo simulation approaches for real-world application assessment. Through systematic expansion and detailed investigation, this Simulink model provides comprehensive understanding and analysis capabilities for MFSK communication systems in fading channel environments.
