MFSK Modulation and Demodulation System in Rayleigh Channel using Simulink

Simulink-based MFSK modulation and demodulation system operating in Rayleigh fading channels, implemented with 8FSK as a baseline example that can be extended to other MFSK variants. The system analysis includes spectrum diagrams, eye patterns, constellation diagrams, and post-demodulation bit error rate (BER) performance evaluation. The implementation demonstrates signal processing algorithms for frequency hopping, orthogonal modulation, and non-coherent detection suitable for fading channels.
