We consider the multi-way relay channel with common messages and full data exchange,
where multiple users exchange correlated messages through a relay. We propose an …

In multiuser wireless communications, interference not only limits the performance of the
system, but also allows users to eavesdrop on other users' messages. Hence, interference …

In this paper, we study the design of network coding for the generalized transmit scheme in
multiple input multiple output Y channel, where K users wish to exchange specified and …

Interference creates a fundamental barrier in attempting to improve throughput in wireless
networks, especially when multiple concurrent transmissions share the wireless medium. In …

In this paper, we investigate the degrees of freedom (DOF) of the Y channel consisting of
three single-antenna users and a two-antenna common access relay, where each user …

This paper investigates the degrees of freedom (DoF) of the L-cluster, K-user MIMO multi-
way relay channel, where users in each cluster wish to exchange messages within the …

Cooperation and interference are two distinct outcomes of the broadcast nature of the
wireless medium. This dissertation investigates the interaction between cooperation and …

In this dissertation, two promising technologies which improve the spectrum efficiency in
wireless networks are investigated: cognitive radio (CR) and relay technology. Cognitive …
