Abstract-- Most existing work on adaptive allocation of subcarriers and power in multiuser OFDM systems has focused on homogeneous traffic consisting of delay-constrained data (gua...
Abstract- In this paper, we investigate the use of a crosslayer allocation mechanism for the high-rate ultra-wideband (UWB) systems. The aim of this paper is twofold. First, throug...
We investigate the packet-level scheduling for the downlink of multiple-input multiple-output (MIMO) multi-user systems using beamforming. We consider the traffic arrival process ...
—OFDM systems are the major cellular platforms for supporting ubiquitous high performance mobile applications. However, there remain a number of research challenges to be tackled...
