Simulation of MC-CDMA Systems

This documentation offers detailed explanations and implementations of MC-CDMA (Multi-Carrier Code Division Multiple Access) system simulations using MATLAB. It covers fundamental principles including multi-carrier modulation techniques, spread spectrum communication, and orthogonal code division multiplexing. The simulation implementation demonstrates key components such as OFDM (Orthogonal Frequency Division Multiplexing) modulation/demodulation using FFT operations, spreading codes generation with Walsh-Hadamard sequences, and channel modeling with additive white Gaussian noise (AWGN). Practical examples include MATLAB code for signal transmission processes, receiver synchronization algorithms, and bit error rate (BER) performance evaluation through Monte Carlo simulations. Step-by-step experimental procedures guide users through parameter configuration, system initialization, and result analysis using MATLAB's communication toolbox functions. This resource serves as a practical reference for understanding MC-CDMA system architecture, implementation techniques, and performance optimization approaches.
