“…By contrast, in multimedia communications, parameters such as the delay or the guarantee of a certain bit rate must be considered, hence the above mentioned schemes must be adapted since different service classes must be guaranteed. M. A. Enright et al have used in their research work in [4] fixed scaling factors applied to the different service classes in order to allow a modified version of the water-filling algorithm to prioritize the different service classes. Moreover, a cross-layer strategy implemented by X. Guoxing et al in [5] has demonstrated that the information from the input buffers is very useful to determine the actual transmission rate and to predict the transmission delays.…”

Abstract:Most of the traditional channel-aware schedulers produce very unfair situations, whereas schedulers based on input buffers state and quality of service requirements lead to low spectrally efficient systems. In this paper a novel radio resource allocation algorithm based on combination of the CSI information as well as the input buffers is presented and applied to a multicarrier system 1 . In fact, the Group Orthogonal MC-CDMA and the Spread Spectrum Multicarrier Multiple Access schemes are analyzed and performances compared when applying the proposed algorithm in a typical low-mobility environment.
