Digital Receiver Modulation and Demodulation MATLAB Implementation

I would like to share the MATLAB programs developed for my master's thesis concerning digital receiver modulation and demodulation. These programs are particularly valuable as they demonstrate practical implementations of key digital communication algorithms including constellation mapping, pulse shaping filters, carrier synchronization, and phase recovery techniques. The codebase provides working examples of QAM/PSK modulation schemes, matched filtering, timing recovery loops, and equalization methods commonly used in modern digital receivers. These implementations serve as an excellent Matlab-based framework that enables researchers and developers to better understand the underlying principles of digital receiver design while facilitating easier experimentation with various modulation/demodulation algorithms. The programs include commented code sections explaining critical functions such as symbol decision logic, error detection mechanisms, and performance evaluation metrics. Therefore, I strongly recommend these implementations to anyone interested in digital receiver modulation/demodulation research and development.
