Communication Tradeoffs in Wireless Networks
Serj Haddad, Olivier Leveque
We characterize the maximum achievable broadcast rate in a wireless network under various fading assumptions. Our result exhibits a duality between the performance achieved in this…
On the Broadcast Capacity of Large Wireless Networks at Low SNR
Serj Haddad, Olivier Leveque
The present paper focuses on the problem of broadcasting information in the most efficient manner in a large two-dimensional ad hoc wireless network at low SNR and under line-of-si…
Spatial degrees of freedom of MIMO systems in Line-of-Sight Environment
Marc Desgroseilliers, Olivier Leveque, Emmanuel Preissmann
While the efficiency of MIMO transmissions in a rich scattering environment has been demonstrated, less is known about the situation where the fading matrix coefficients come from…
Linear Capacity Scaling in Wireless Networks: Beyond Physical Limits?
Ayfer Ozgur, Olivier Leveque, David Tse
We investigate the role of cooperation in wireless networks subject to a spatial degrees of freedom limitation. To address the worst case scenario, we consider a free-space line-of…
Diversity-Multiplexing Tradeoff for the MIMO Static Half-Duplex Relay
Olivier Leveque, Christophe Vignat, Melda Yuksel
In this work, we investigate the diversity-multiplexing tradeoff (DMT) of the multiple-antenna (MIMO) static half-duplex relay channel. A general expression is derived for the DMT…
Information Theoretic Operating Regimes of Large Wireless Networks
Ayfer Ozgur, Ramesh Johari, David Tse +1
In analyzing the point-to-point wireless channel, insights about two qualitatively different operating regimes--bandwidth- and power-limited--have proven indispensable in the desig…
