MATLAB Implementation of Digital Communications

This documentation describes my learning journey in digital communications and the corresponding simulation programs I've developed. I created comprehensive MATLAB simulations while studying the fundamental concepts from John G. Proakis' "Digital Communications" textbook. The implementations cover various digital communication systems including modulation techniques (PSK, QAM, FSK), channel coding algorithms, and receiver design principles. The codebase features modular implementations of core digital communication components such as pulse shaping filters, matched filters, error correction coding (convolutional and block codes), and synchronization algorithms. Each simulation includes parameter configuration files and visualization modules to analyze system performance through BER calculations and constellation diagrams. I'm sharing these implementations to facilitate knowledge exchange and collaborative learning. If you identify any errors, inaccuracies, or optimization opportunities in the code logic or mathematical implementations, please provide constructive feedback. Through technical discussions and code reviews, we can collectively enhance our understanding of digital communication systems and improve the educational quality of these simulations.
