Abstract
In this paper, a Dynamic Subcarrier Allocation (DSA) framework is presented for the Single Carrier Frequency Division Multiple Access (SC-FDMA) system. Taking advantages of utility function, the proposed DSA framework evaluates the benefit of certain scheduling, and optimizes the established utility-pricing system thereby satisfying the transmission equipments of each service. Based on this architecture, the Proportional Fair (PF) algorithm, Largest Weighted Delay First (M-LWDF) algorithm and the Max-delay-utility (MDU) algorithm are compared in terms of three aspects: delay violation probability, loss probability and delay variance. Simulation results indicate that the MEU algorithm is superior to the M-LWDF algorithm, and the PF algorithm achieves the worst Quality of Service (QoS) performance.
