Orthogonal frequency division multiple access in WiMAX and LTE — A comparison

Abstract

Orthogonal frequency division multiple access (OFDMA) has been adopted by all the proposals which have been considered for the fourth generation (4G) wireless technologies. Specifically, the two main contenders in the 4G marketplace are likely to be evolutions of WiMAX and LTE. In this work, we compare the use of OFDMA in these standards.
