On the Optimal Number of Cooperative Base Stations in Network MIMO
Jakob Hoydis, Mari Kobayashi, Merouane Debbah
We consider the multi-cell uplink (network MIMO) where M base-stations (BSs) communicate simultaneously with M user terminals (UTs). Although the potential benefit of multi-cell co…
Asynchronous CDMA Systems with Random Spreading-Part I: Fundamental Limits
Laura Cottatellucci, Ralf R. Mueller, Merouane Debbah
Spectral efficiency for asynchronous code division multiple access (CDMA) with random spreading is calculated in the large system limit allowing for arbitrary chip waveforms and fr…
Asynchronous CDMA Systems with Random Spreading-Part II: Design Criteria
Laura Cottatellucci, Ralf R. Mueller, Merouane Debbah
Totally asynchronous code-division multiple-access (CDMA) systems are addressed. In Part I, the fundamental limits of asynchronous CDMA systems are analyzed in terms of spectral ef…
Distributed Coalition Formation Games for Secure Wireless Transmission
Walid Saad, Zhu Han, Tamer Basar +2
Cooperation among wireless nodes has been recently proposed for improving the physical layer (PHY) security of wireless transmission in the presence of multiple eavesdroppers. Whil…
Spatial games and global optimization for mobile association problems
Alonso Silva, Hamidou Tembine, Eitan Altman +1
The basic optimal transportation problem consists in finding the most effective way of moving masses from one location to another, while minimizing the transportation cost. Such co…
Magnetworks: how mobility impacts the design of Mobile Networks
Alonso Silva, Eitan Altman, Merouane Debbah +1
In this paper we study the optimal placement and optimal number of active relay nodes through the traffic density in mobile sensor ad-hoc networks. We consider a setting in which a…
