Abstract
A simulative performance evaluation of a cellular mobile radio system based on Orthogonal Frequency Division Multiple Access (OFDMA) is presented in this paper. The impact of using either distributed or adjacent OFDMA subchannels is investigated concerning both throughput and delay. This incorporates the exploitation of multi-user diversity and uncertainty in the subchannel quality estimation due to fading and interference. The performance analysis is conducted by means of stochastic event-driven simulations. The presented results can be considered as a basic contribution to the understanding of the behavior of OFDMA based dynamic resource allocation in cellular environments.
