Communication System Simulation Programs (MATLAB) with Modulation and Coding Implementations

This collection contains MATLAB simulation programs for communication systems, featuring implementations of various modulation techniques such as QPSK, MPSK, and BPSK with detailed constellation mapping and demodulation algorithms. The toolkit also includes simulations for common channel coding and decoding techniques, incorporating convolution codes and error correction codes with MATLAB's communication toolbox functions for encode/decode operations. These simulations enable researchers and engineers to analyze system performance through BER calculations, SNR sweeps, and eye diagram visualizations. The programs offer flexible parameter configuration options through structured MATLAB scripts, allowing users to customize parameters like modulation order, code rates, and channel models through editable configuration sections. Each simulation includes commented code explaining key algorithmic steps, such as symbol mapping for modulation schemes and Viterbi algorithm implementation for decoding processes. This resource serves as a practical tool for studying communication system principles with hands-on MATLAB experimentation capabilities.
