Resumen

In this paper a new permutation zone which combines adjacent and distributed subcarrier permutation is proposed for Orthogonal Frequency Division Multiple Access (OFDMA) systems. For such purpose two types of burst are defined: localized and distributed. A new resource allocation and scheduling algorithm that exploits such structure is then proposed. Furthermore, the effects of limited feedback are also investigated where only the n-best subchannel quality metrics are feedback. As shown in the simulation results, a tradeoff between spectral efficiency, delay and load signaling requirements is obtained which can be adjusted by modifying the number of subchannels signaled in the uplink. Additionally, the proposed scheme turns out to be a very efficient way to increase the system fairness and therefore improving the quality of service.
