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…
From Spectrum Pooling to Space Pooling: Opportunistic Interference Alignment in MIMO Cognitive Networks
S. M. Perlaza, N. Fawaz, S. Lasaulce +1
We describe a non-cooperative interference alignment (IA) technique which allows an opportunistic multiple input multiple output (MIMO) link (secondary) to harmlessly coexist with…
Physical Layer Security: Coalitional Games for Distributed Cooperation
Walid Saad, Zhu Han, Tamer Basar +2
Cooperation between wireless network nodes is a promising technique for improving the physical layer security of wireless transmission, in terms of secrecy capacity, in the presenc…
On the Compound MIMO Broadcast Channels with Confidential Messages
Mari Kobayashi, Yingbin Liang, Shlomo Shamai +1
We study the compound multi-input multi-output (MIMO) broadcast channel with confidential messages (BCC), where one transmitter sends a common message to two receivers and two conf…
Secured Communication over Frequency-Selective Fading Channels: a practical Vandermonde precoding
Mari Kobayashi, Merouane Debbah, Shlomo Shamai
In this paper, we study the frequency-selective broadcast channel with confidential messages (BCC) in which the transmitter sends a confidential message to receiver 1 and a common…
Large System Analysis of Linear Precoding in Correlated MISO Broadcast Channels under Limited Feedback
Sebastian Wagner, Romain Couillet, Merouane Debbah +1
In this paper, we study the sum rate performance of zero-forcing (ZF) and regularized ZF (RZF) precoding in large MISO broadcast systems under the assumptions of imperfect channel…
A Deterministic Equivalent for the Analysis of Correlated MIMO Multiple Access Channels

In this article, novel deterministic equivalents for the Stieltjes transform and the Shannon transform of a class of large dimensional random matrices are provided. These results a…
Asymptotic Capacity and Optimal Precoding in MIMO Multi-Hop Relay Networks
Nadia Fawaz, Keyvan Zarifi, Merouane Debbah +1
A multi-hop relaying system is analyzed where data sent by a multi-antenna source is relayed by successive multi-antenna relays until it reaches a multi-antenna destination. Assumi…
