Complete WCDMA Simulation MATLAB Code

This MATLAB code provides a complete WCDMA (Wideband Code Division Multiple Access) simulation framework for modeling wireless communication signal transmission and processing. The implementation includes detailed modules for channel setup, encoding, modulation, demodulation, decoding, channel estimation, and symbol detection algorithms. Key functional components implement CDMA spreading techniques using orthogonal variable spreading factor codes, Rake receiver implementation for multipath signal combining, and turbo coding/decoding schemes for error correction. Users can analyze system performance through BER (Bit Error Rate) calculations, study interference effects, and evaluate different channel conditions. The modular code structure allows for easy customization and extension to support various simulation scenarios, algorithm comparisons, and research applications. Developers can modify parameters such as spreading factors, channel models, and power control algorithms to suit specific research requirements.
