Abstract—The high peak-to-average-power ratio (PAR) of Orthogonal Frequency Division Multiplexing (OFDM) transmission systems significantly reduces the power efficiency or perf...
—Dense deployments of hybrid WLANs result in high levels of interference and low end-user throughput. Many frequency allocation mechanisms for WLANs have been proposed by a large...

— We consider the problem of rate allocation in a fading Gaussian multiple-access channel with fixed transmission powers. The goal is to maximize a general concave utility funct...
—Suboptimal detection schemes, such as list MIMO detection, often face the challenge of having to “guess” at the decision reliability for some of the detected bits. A simple ...

Abstract—In this paper, we review the most important performance characteristics of the 802.11 DCF wireless networks, point out some false common knowledge, and report on recent ...
