OFDMA Simulation Code Implementation on MATLAB Platform

This MATLAB-based OFDMA simulation code provides a comprehensive implementation of Orthogonal Frequency Division Multiple Access (OFDMA), a multi-user wireless communication technology that enables simultaneous data transmission for multiple users while improving spectral efficiency of the system. The simulation framework allows dynamic adjustment and optimization of various OFDMA system parameters including subcarrier allocation schemes, power distribution algorithms, and user scheduling protocols. Through MATLAB's computational capabilities, researchers can efficiently model OFDMA systems with features such as adaptive modulation coding (AMC), resource block assignment using greedy algorithms or proportional fair scheduling, and interference management techniques. The code structure includes key functions for signal generation, IFFT/FFT operations for orthogonal subcarrier implementation, cyclic prefix insertion for multipath mitigation, and bit error rate (BER) performance analysis. This simulation platform serves as a powerful tool for wireless communication research and development, enabling detailed system performance evaluation under various channel conditions and configuration scenarios.
