Power Control and Resource Allocation in TDD-OFDM Based Femtocell Networks with Interference
(IEEE, 2017)Femtocell technology is a promising solution for different dilemmas in cellular networks. In femtocell power control the interference experienced by the network is divided into two main tiers according to the type of network ... -
Power Control-Based Multi-User Li-Fi Using A Compound Eye Transmitter
(IEEE, 2015)In visible light communications (VLC) the transmitted signal is non-negative and real valued and these characteristics constrain the signal space and provide new challenges for waveform design in a multi-user system. In ... -
Power transfer networks at RF frequencies "New design procedures with implementation roadmap"
(IEEE, 2006)The purpose of this work is to provide the necessary background to design wide-band power transfer two-ports, or so-called broadband matching networks, at radio frequencies for wireless communication systems. The importance ... -
Precoded single-cell multi-user MISO visible light communications
(Institute of Electrical and Electronics Engineers Inc., 2015)This study investigates the effects of transmitter and receiver parameters on the performance of a precoded singlecell (SC) multi-user (MU) multi-input-single-output (MISO) visible light communication (VLC) system. A ... -
Production of electron-positron pairs by nuclear dissociation in peripheral heavy ion collisions
(Elsevier, 2007)The STAR Collaboration at the Relativistic Heavy Ion Collider present data on electron-positron pair production accompanied by nuclear breakup at small impact parameters where the simultaneous excitation of the two ions ... -
