MATLAB Source Code for Various Modulation Techniques

The provided collection includes MATLAB source codes implementing various modulation techniques such as BASK, BFSK, BPSK, MSK, QPSK, and a Rayleigh channel model. These implementations feature key algorithms including carrier wave generation, symbol mapping, constellation diagram plotting, and signal demodulation processes. The codes serve as practical educational tools for understanding modulation principles and simulating communication systems under different channel conditions. For enhanced learning, we recommend consulting relevant research papers and technical literature to deepen your understanding of underlying theories and practical applications. Furthermore, users can modify system parameters like carrier frequency, symbol rate, and signal-to-noise ratio to adapt these implementations for specific research scenarios or performance analysis. The Rayleigh model file (raymodel.m) specifically implements fading channel characteristics using complex Gaussian random variables to simulate multipath propagation effects.
