This paper studies the secure degree of freedom (SDOF) of the multiway relay wiretap
system K-user MIMO Y wiretap channel, where each legitimate user equipped with M …

Interference alignment (IA) has been shown as an important technique to achieve a linear
capacity scaling in wireless communications. However, the IA scheme over finite signaling …

This paper studies the beamforming design for the multiple-input multiple-output (MIMO)
multiway relay channel with clustered full data exchange. We formulate the linear signal …

In multi user Gaussian relay networks, it is desirable to transmit private information to each
user as well as common information to all of them. However, the capacity region of such …

This paper investigates the weighted sum degrees of freedom (DoF) of the MIMO Y channel
that consists of three users, where the j-th user is equipped with M j antennas, and a relay …

Although there have been many researches and corresponding degrees of freedom (DoF)
analysis on multiple pairwise users exchanging data by one-hop relaying through one or …

This thesis studies the multiuser interference problem in large-scale wireless systems,
where multiple users interfere with each other due to simultaneous transmission. This thesis …
