Detailed Documentation

This project presents a MATLAB simulation of CDMA transmission systems operating under AWGN multipath fading channel conditions. The simulation employs MATLAB to model CDMA signal transmission while accounting for multipath propagation effects and additive white Gaussian noise interference. We will investigate multipath propagation characteristics and noise impacts in CDMA channels to better understand channel performance and behavioral properties. The implementation includes key components such as: - Walsh code generation for channel spreading - RAKE receiver implementation for multipath signal combining - AWGN noise injection using randn() function - Multipath channel modeling with delay profiles and fading coefficients Through this simulation, researchers can conduct in-depth studies of CDMA system performance and develop optimization strategies for improved signal reliability and capacity enhancement.
