We study the degrees of freedom (DOF) of a multiple-input multiple-output (MIMO) two-way
X relay channel, where there are two groups of source nodes and one relay node, each …

Two-way relaying reduces the loss in spectral efficiency caused in a conventional half-
duplex relay due to two channel uses per data unit transmitted to the destination. Two-way …

In this paper, we propose a new three-user network information flow model, referred to as
the triangular multiple-input-multiple-output (MIMO) relay (TMR) channel, which consists of …

An asymmetric multi‐way relay communication scheme using orthogonal projection and
analogue network coding is proposed. The scheme is designed for the wireless sensor …

Physical-layer network coding (PNC) is an attractive approach to increasing the network
throughput by exploiting the broadcast nature of wireless channels. This thesis focuses on …

Multi-way relaying is a cooperative scheme for communication scenarios where several
users want to share their data with each other. While the capacity of multi-way relay …

Many telecommunication operators around the world have multiple networks. The networks
run by each operator are always of different generations, such as 2G and 3G or even 4G …

Ultra-wideband (UWB) communication enables license-exempt transmission with very low
power over large bandwidths. The technology can provide very high data rates over short …
