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…
On the Degrees of Freedom of Finite State Compound Wireless Networks - Settling a Conjecture by Weingarten et. al
Tiangao Gou, Syed A. Jafar, Chenwei Wang
We explore the degrees of freedom (DoF) of three classes of finite state compound wireless networks in this paper. First, we study the multiple-input single-output (MISO) finite st…
On Degrees of Freedom Region of MIMO Networks without CSIT
Chiachi Huang, Syed A. Jafar, Shlomo Shamai +1
In this paper, we study the effect of the absence of channel knowledge for multiple-input-multiple-output (MIMO) networks. Specifically, we assume perfect channel state information…
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…
The Diversity Multiplexing Tradeoff for Interference Networks
Aydin Sezgin, Syed Ali Jafar, Hamid Jafarkhani
The diversity-multiplexing tradeoff (DMT) for interference networks, such as the interference channel, the X channel, the Z interference channel and the Z channel, is analyzed. In…
Capacity of a Class of Symmetric SIMO Gaussian Interference Channels within O(1)
Tiangao Gou, Syed A. Jafar
The N+1 user, 1 x N single input multiple output (SIMO) Gaussian interference channel where each transmitter has a single antenna and each receiver has N antennas is studied. The s…
