MATLAB Code Implementation for 16QAM Simulation

This simulation program provides a complete implementation of 16QAM (16-Quadrature Amplitude Modulation) featuring several key communication system visualizations including carrier signal analysis, eye diagrams, and constellation plots. The code employs MATLAB's digital communication toolbox functions such as qammod for modulation, comm.EyeDiagram for eye pattern generation, and scatterplot for constellation visualization. Through this simulation, engineers can gain deeper insights into 16QAM modulation techniques and their applications in communication systems. The implementation includes algorithms for signal generation, noise addition using awgn function, and error rate calculation using berawgn. Simulation results enable system parameter optimization through performance analysis metrics like bit error rate (BER) and signal-to-noise ratio (SNR) relationships. This makes the simulation program an essential tool for researchers and engineers developing and optimizing 16QAM-based communication systems, with code structured to allow easy modification of modulation parameters and channel conditions for various testing scenarios.
