Multicell processing in the form of joint encoding for the downlink of a cellular system is
studied under the assumption that the base stations (BSs) are connected to a central …

This paper studies the two-hop relay broadcast channel (BC) for a relay-assisted wireless
cellular network where the multiuser independent downlink signals from the base station …

A power allocation or scheduling problem is studied for a multiuser multiple-input multiple-
output (MIMO) wireless relay system where there is a non-regenerative relay between one …

Interference is a common impairment in wireless communication systems. Multi-hop relay
networks use a set of intermediate nodes called relays to facilitate communication between …

In this paper, we consider the amplify-and-forward relaying transmission in the downlink of a
multi-channel cellular network with one base station and multiple relay-destination pairs …

The paper considers a network scenario in which multiple source-destination node pairs
need to communicate simultaneously. Each source and destination is equipped with one …

Uplink-downlink duality refers to the fact that under a sum-power constraint, the capacity
regions of a Gaussian multiple-access channel and a Gaussian broadcast channel with …

In this paper, we propose a robust minimum mean square error (MMSE)-based
beamforming technique for multiantenna relay broadcast channels, where a multiantenna …

In wireless relay networks, noise at the relays can be correlated possibly due to common
interference or noise propagation from preceding hops. A parallel relay network with noise …

In this work, we consider a two-hop multiuser amplify-and-forward relay network with multi-
antenna nodes. The results are three-fold. First, for any relay amplification matrix D in the …
