A father protocol for quantum broadcast channels
, 2012 A new protocol for quantum broadcast channels based on the fully quantum Slepian-Wolf protocol is presented. The protocol yields an achievable rate region for entanglement-assisted transmission of quantum information through a quantum broadcast channel ...

Multi-Cell Random Beamforming: Achievable Rate and Degrees of Freedom Region
, 2013 Random beamforming (RBF) is a practically favourable transmission scheme for multiuser multi-antenna downlink systems since it requires only partial channel state information (CSI) at the transmitter.

Space-Time Block Diagonalization for Frequency-Selective MIMO Broadcast Channels
IEEE Access, 2016 The most important linear precoding method for frequency-flat MIMO broadcast channels is block diagonalization (BD) which, under certain conditions, attains the same nonlinear dirty paper coding channel capacity.

Hepatitis C in Children—An Asia–Pacific Concise Perspective
PathogensSince the discovery of hepatitis C virus (HCV) in 1989, we now have curative treatment options with direct-acting antiviral therapies. By increasing the rate of treatment and reducing transmission, the eradication of HCV is potentially achievable ...

Multiaccess Channels with State Known to Some Encoders and Independent Messages
EURASIP Journal on Wireless Communications and Networking, 2008 We consider a state-dependent multiaccess channel (MAC) with state noncausally known to some encoders. For simplicity of exposition, we focus on a two-encoder model in which one of the encoders has noncausal access to the channel state.

Subcarrier-Index Modulation Aided OFDM - Will It Work?
IEEE Access, 2016 The achievable performance of subcarrier-index modulation (SIM) is analyzed in terms of its minimum Euclidean distance, constrained and unconstrained average mutual information, as well as its peak-to-average power ratio (PAPR).

Slotted Gaussian Multiple Access Channel: Stable Throughput Region and Role of Side Information
EURASIP Journal on Wireless Communications and Networking, 2008 We study the relation between the stable throughput regions and the capacity regions for a Gaussian multiple-access channel. Our main focus is to study how the extent of side information about source arrival statistics and/or instantaneous queue states ...
