Complete WCDMA System Simulation with MATLAB Code

I require a complete WCDMA system simulation MATLAB code implementation containing the following core components: channel modeling, multipath channel transmission, modulation/demodulation processes, and signal detection techniques. This simulation code will be utilized for comprehensive research on WCDMA system performance and functionality analysis. The implementation should include: - Channel modeling with path loss calculations and fading characteristics using Rayleigh or Rician distribution models - Multipath channel transmission simulation with configurable delay spreads and Doppler effects - WCDMA-specific modulation schemes (QPSK) with spread spectrum techniques using OVSF codes - RAKE receiver implementation for multipath signal combining and interference cancellation - Signal detection algorithms incorporating matched filters and error rate calculations - Power control simulation and interference analysis modules The code structure should feature modular design with separate functions for each subsystem, parameter configuration files, and performance visualization tools for BER vs SNR plots and system capacity analysis.
