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…
Duality and Capacity Region of AF Relay MAC and BC
Syed A. Jafar, Krishna S. Gomadam
We consider multi-hop multiple access (MAC) and broadcast channels (BC) where communication takes place with the assistance of relays that amplify and forward (AF) their received s…
