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...
Spatial scheduling in a heterogeneous WiMax Downlink channel, based on partial Channel State Information at the Transmitter (CSIT), is carried out through a multibeam opportunistic...
Abstract— Performance analysis of multiuser orthogonal frequency division multiplexing (OFDM-TDMA) and orthogonal frequency division multiple access (OFDMA) networks in support o...
Abstract— In this paper we study the effects of practical pilotassisted channel state estimation on the achievable information theoretic data rates (uplink and downlink) in a mul...
Abstract— We consider both the single-user and the multiuser power allocation problems in MIMO systems, where the receiver side has the perfect channel state information (CSI), a...
