Abstract In this paper, an adaptive resource allocation scheme of multi-service subcarrier adjusting and borrowing for multi-user OFDM-based systems is proposed. According to channel fading condition and quality of service of users, the scheme is used to maximize the system capacity and performance by adjusting and borrowing subcarrier among multi-service. The simulation results illustrate that the scheme proposed in this paper can improve performance OFDM-based systems.
