Multiuser adaptive subcarrier-and-bit allocation with adaptive cell selection for OFDM systems.

Multiuser adaptive subcarrier-and-bit allocation with adaptive cell selection for OFDM systems.

Adaptive resource allocation has been identified as one of the key technologies for providing efficient utilization of the limited power and spectrum in future wireless systems. In this paper, an adaptive resource allocation methodology is proposed for cellular orthogonal frequency division multiple...
