CDMA System Simulation Using MATLAB

This project provides comprehensive MATLAB source code implementations for various CDMA system modules, including channel coding, convolutional encoding, interleaving, modulation, demodulation, and turbo decoding processes. The simulation approach involves developing individual module source programs in MATLAB, followed by implementing convolutional interleaving, modulation/demodulation operations, and advanced decoding techniques. Key implementation aspects include: - Channel coding modules featuring error correction algorithms - Convolutional encoding with specified constraint lengths and generator polynomials - Block and convolutional interleaving techniques for burst error protection - Digital modulation schemes (such as QPSK or 16-QAM) with corresponding demodulators - Turbo decoding implementation using iterative MAP (Maximum A Posteriori) algorithms The MATLAB-based simulation enables comprehensive analysis of CDMA system performance, allowing researchers to study bit error rates, system capacity, and interference characteristics under various channel conditions. This modular approach facilitates testing individual components and their interactions within the complete CDMA communication chain.
