In this work the transmit covariance matrix optimization problem for the discrete memoryless
MIMO Gaussian bidirectional broadcast channel is studied. A half-duplex relay node …

In this work, the MIMO Gaussian bidirectional broadcast channel (BBC) with common
messages is studied. The problem is motivated by the concept of bidirectional relaying in a …

In the work at hand relevant issues concerning implementation of optimal and nearly optimal
transmission approaches for the MIMO OFDM broadcast channel are discussed. In …

We consider the broadcast phase of a three-node network, where a relay node establishes a
bidirectional communication between two nodes using a spectrally efficient two-phase …

In a three-node network bidirectional communication between two nodes can be enabled by
a half-duplex relay node with a decode-and-forward protocol. In the first phase, the …

For Gaussian multiple-input multiple-output (MIMO) relay channels with partial decode-and-
forward, the optimal type of input distribution is still an open question in general. Recent …

A Gaussian multiple-input multiple-output broadcast channel (MIMO GBC) is considered.
Throughout the paper it is assumed that 1) input signals are Gaussian and 2) perfect …

Parallel multiple-input multiple-output (MIMO) broadcast channels have been shown to be
separable from an information theoretic point of view, ie, capacity can be achieved with a …

In this work we consider the achievable rates of a joint resource allocation for a three-node
network where a half-duplex relay node enables bidirectional communication between …

This paper considers the multiantenna broadcast channel without transmit-side channel
state information. For this channel, it has been known that when all receivers have channel …
