16QAM MATLAB Source Code

This MATLAB source code provides a comprehensive implementation of 16QAM (16-Quadrature Amplitude Modulation) with detailed programming components. The code includes thorough signal power spectrum analysis to evaluate transmission performance characteristics, signal constellation diagram generation for visualizing signal point distribution in the I-Q plane, and comprehensive bit error rate analysis to assess transmission reliability under various channel conditions. Through this implementation, you'll gain deep insights into 16QAM modulation techniques, including the algorithm for mapping binary data to 16 distinct constellation points. The power spectrum analysis function demonstrates how to calculate and visualize frequency domain characteristics using FFT-based methods. The constellation plotting module shows the implementation of scatter plots for signal representation, while the BER analysis includes Monte Carlo simulation approaches for evaluating system performance under noise conditions. This source code offers a complete learning opportunity to understand 16QAM system design, featuring practical implementations of modulation/demodulation algorithms, signal processing techniques, and performance evaluation metrics commonly used in digital communication systems.
