Radio Resource Allocation in Mc-Cdma Under QOS Requirements.

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 This work has been partially carried out in the framework of the Celtic project WISQUAS (CP-2-035), and in the national Spanish code project: FIT-330220- 2005-108. 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.
