METHOD OF COST-BASED ADAPTIVE RESOURCE ALLOCATION IN OFDMA SYSTEMS

摘要

the present invention is an orthogonal frequency division multiple access system, the cost function based on an adaptive resource allocation in , a ) using the cost function sorts the sub- packets are transmitted , and each user , allocating the alignment of the sub- packet to each of the sub-channel ; And b) characterized in that it comprises the step of assigning each of the power according to the state of the sub- channel .
