Degrees of Freedom of Multi-Source Relay Networks
Sang-Woon Jeon, Sae-Young Chung, Syed A. Jafar
We study a multi-source Gaussian relay network consisting of source--destination pairs having unicast sessions. We assume layers of relays between the sources and the d…
Optimal Multiplexing Gain of K-user Line-of-Sight Interference Channels with Polarization
Sung ho Chae, Sang Won Choi, Sae-Young Chung
We consider the multiplexing gain (MUXG) of the fully connected K-user line-of-sight (LOS) interference channels (ICs). A polarimetric antenna composed of 3 orthogonal electric dip…
On the Beamforming Design for Efficient Interference Alignment
Sang Won Choi, Syed A. Jafar, Sae-Young Chung
An efficient interference alignment (IA) scheme is developed for -user single-input single-output frequency selective fading interference channels. The main idea is to steer the…
Sum capacity of multi-source linear finite-field relay networks with fading
Sang-Woon Jeon, Sae-Young Chung
We study a fading linear finite-field relay network having multiple source-destination pairs. Because of the interference created by different unicast sessions, the problem of find…
On the Separability of Parallel Gaussian Interference Channels
Sang Won Choi, Sae-Young Chung
The separability in parallel Gaussian interference channels (PGICs) is studied in this paper. We generalize the separability results in one-sided PGICs (OPGICs) by Sung \emph{et al…
Capacity of the Gaussian Two-way Relay Channel to within 1/2 Bit
Wooseok Nam, Sae-Young Chung, Yong H. Lee
In this paper, a Gaussian two-way relay channel, where two source nodes exchange messages with each other through a relay, is considered. We assume that all nodes operate in full-d…
