Implementation of 8QAM Modulation Using MATLAB

This project demonstrates 8QAM modulation implementation using MATLAB simulation software. The orthogonal amplitude modulation approach is employed where the I-coordinate projection of constellation points modulates the in-phase carrier amplitude, while the Q-coordinate projection modulates the quadrature carrier amplitude. The final modulated signal is obtained by summing both amplitude-modulated components. The implementation includes constellation mapping, carrier generation, and signal combination using MATLAB's vector operations and plotting functions.
