MATLAB Simulation of BCH Codes with Configurable Modulation Schemes

This MATLAB simulation framework enables comprehensive experimentation with BCH codes while supporting various modulation schemes such as BPSK, 4QAM, and 16QAM. The implementation allows researchers to systematically evaluate error correction performance across different signal constellations. Key implementation features include: - Modular code structure separating encoding, modulation, channel modeling, and decoding components - Built-in BER (Bit Error Rate) calculation functions for performance comparison - Configurable signal-to-noise ratio (SNR) ranges for comprehensive analysis - Support for both hard-decision and soft-decision decoding algorithms The simulation utilizes MATLAB's Communication Toolbox functions for efficient BCH encoding/decoding (bchenc/bchdec) and digital modulation/demodulation (pskmod/pskdemod, qammod/qamdemod). Users can easily modify parameters like code length, error correction capability, and modulation order to study the trade-offs between spectral efficiency and error correction performance in different channel conditions.
