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. 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.
