Abstract: A simplified adaptive resource allocation algorithm is proposed.The algorithm can maximize throughput of OFDMA system and ensure fairness of users,and it has a low computational complexity.It splits the whole allocation into two steps,which include the first subcarrier allocation based on fairness principle and the subsequent power allocation by waterfilling method.The simulation results show that compared with fixed allocation method,the adaptive resource allocation algorithm proposed in this paper could remarkably improve spectral efficiency of OFDM system.

Key words: OFDM, adaptive resource allocation, fairness principle
