When two or more users in a wireless network transmit simultaneously, their electromagnetic
signals are linearly superimposed on the channel. As a result, a receiver that is interested in …

Lattice codes are known to achieve capacity in the Gaussian point-to-point channel,
achieving the same rates as iid random Gaussian codebooks. Lattice codes are also known …

The multiway relay channel is a multicast network where L users exchange data through a
relay. In this paper, the capacity region of a class of multiway relay channels is derived …

Two transmission strategies, namely (i) pairwise zero-forcing transmission and (ii) non-
pairwise zero-forcing transmission, for multiple-input multiple-output (MIMO) amplify-and …

This book provides a consolidated view of the various network coding techniques to be
implemented at the design of the wireless networks for improving its overall performance. It …

The degrees of freedom (DoF) of the MIMO Y-channel, a multi-way communication network
consisting of 3 users and a relay, are characterized for arbitrary number of antennas. The …

The symmetric two-user Gaussian interference relay channel (IRC) is studied from a
generalized degrees of freedom (GDoF) perspective. While it is known that the relay does …

We consider a multi-way relay network with multiple users exchanging information with each
other via a multi-antenna relay. The multi-way relaying strategy consists of one multiple …

Throughput and energy efficiency in 3-way relay channels are studied in this paper. Unlike
previous contributions, we consider a circular message exchange. First, an outer bound and …

We study an asymmetric multi-way relay channel where users have different channel
conditions. To enable data exchange between the users, an existing practical approach …
