Multi-User Resource Allocation Algorithms for OFDMA Systems

This paper presents detailed MATLAB implementation code for multi-user resource allocation algorithms in OFDMA systems, serving as an outstanding educational resource for beginners. Beyond explaining fundamental algorithmic principles, it includes practical applications and case studies to help readers better understand and implement these algorithms. The MATLAB code demonstrates key implementation aspects such as subcarrier allocation methods, power distribution strategies, and fairness optimization techniques. Additionally, the paper provides extensive visualizations and experimental results, including performance comparison charts and resource allocation diagrams, to help readers intuitively understand algorithm performance and effectiveness. The implementation covers essential functions for handling multiple user scenarios, channel state information processing, and optimization constraint management. Whether for academic research or engineering practice, this paper serves as an indispensable reference, particularly for those developing resource allocation solutions in 4G/5G networks and beyond.
