We consider the two-user multiple-input multipleoutput (MIMO) interference channel with confidential messages (ICCM). We determine the exact secure degrees of freedom (sdof) …
The downlink of symmetric Cloud Radio Access Networks (C-RANs) with multiple relays and a single receiver is studied. Lower and upper bounds are derived on the capacity. The lower …
R Fritschek, G Wunder - IEEE Transactions on Information …, 2018 - ieeexplore.ieee.org
We study deterministic approximations of the Gaussian two-user multiple access wiretap channel (G-MAC-WT) and the Gaussian wiretap channel with a helper (G-WT-H). These …

In this paper, we study outer bounds on the capacity region of the downlink multicell processing model with finite backhaul capacity for the simple case of two base stations and …
SH Lee, A Khisti - IEEE Transactions on Information Theory, 2018 - ieeexplore.ieee.org
In this paper, we study a diamond-relay channel where the source is connected to M relays through orthogonal links and the relays transmit to the destination over a wireless multiple …

Wireless communications are highly susceptible to eavesdropping due to their inherent broadcast nature. Recent works have proposed the use of interference for impeding the …
SH Lee, A Khisti - IEEE Communications Letters, 2016 - ieeexplore.ieee.org
In this letter, we consider the Gaussian diamond-wiretap channel with conferencing links between relays for the following three cases: 1) both conferencing links are confidential; 2) …
SH Lee, A Khisti - IEEE Communications Letters, 2016 - ieeexplore.ieee.org
In this letter, we establish the secure degrees-of-freedom of the Gaussian diamond-wiretap channel with rate-limited relay cooperation, where the eavesdropper not only observes the …
Y Fan, X Wang, X Liao - IEEE Transactions on …, 2019 - ieeexplore.ieee.org
We investigate the secure degrees of freedom (SDoF) for the two-way 2× 2× 2 MIMO interference channel (IC) under three wiretap models, ie, the confidential messages (CM) …
