MC-CDMA System Simulation Implementation using MATLAB or C Programming

This project implements a complete MC-CDMA (Multi-Carrier Code Division Multiple Access) system simulation using either MATLAB or C programming languages. The simulation framework provides deep insights into MC-CDMA system operations and performance characteristics through executable code implementations. The simulation system comprises several key modular components programmed to mimic real-world scenarios. Core modules include user signal generation algorithms that create orthogonal codes for multiple users, multipath channel modeling using Rayleigh or Rician fading models, and sophisticated channel estimation techniques such as Least Squares or Minimum Mean Square Error (MMSE) estimators. The implementation features multi-user detection algorithms including conventional matched filter detection, decorrelating detectors, and more advanced MMSE detectors to handle interference. The system performance is evaluated through Bit Error Rate (BER) calculations against varying Signal-to-Noise Ratio (SNR) conditions, enabling quantitative analysis of system robustness. Key programming aspects involve matrix operations for spreading code generation, Fast Fourier Transform (FFT) implementations for multi-carrier modulation, and iterative algorithms for receiver optimization. The code architecture allows modular parameter adjustments for exploring different scenarios - users can modify spreading factors, carrier frequencies, channel conditions, and detection algorithms through configurable parameters. This simulation platform serves as an excellent educational and research tool for understanding CDMA technology fundamentals, testing newalgorithm variations, and optimizing system designs before practical implementations. The MATLAB version leverages built-in communication toolbox functions while the C implementation demonstrates low-level algorithm optimization for embedded system applications.
