MATLAB Simulation Module for Differential Pulse Code Modulation (DPCM) - Full Implementation of Sampling, Quantization, Prediction, Encoding and Decoding

This documentation presents a comprehensive MATLAB simulation module for Differential Pulse Code Modulation (DPCM). The simulation implements the complete DPCM chain including signal sampling using fixed interval sampling algorithms, quantization with configurable quantization levels, predictive coding using previous sample values, encoding with differential bit representation, and reconstruction through decoding processes. The module features adjustable parameters for sampling rates, quantization bits, and prediction coefficients, allowing users to experiment with different configurations. The code implementation utilizes MATLAB's signal processing toolbox for efficient computation and includes visualization functions for analyzing quantization error and signal reconstruction quality. This educational tool is ideal for understanding DPCM principles, analyzing compression performance, and studying digital communication systems. Feel free to download and use this personally developed module for your academic or research projects. Best wishes for your learning journey!
