The algorithms of the PHY layer may lead to the data loss and the waste of resource for multi-service OFDM system.
In order to resole this problem, a joint MAC-PHY layer resource allocation algorithm is proposed in this paper. The
service model of multi-service OFDM system is analyzed briefly first. After establishing the membership functions of
time delay urgency and rate fairness, the scheduling algorithm of the MAC layer based on triangle module operator is
proposed. Finally the allocation algorithm of the PHY layer is also designed. The simulation results of packet loss
ratio, average waiting delay and rate show that the proposed algorithm can meet the requirement for time delay and
rate fairness, raise the spectrum efficiency and improve the quality of service.
