Algebraic reduction for space-time codes based on quaternion algebras
Laura Luzzi, Ghaya Rekaya-Ben Othman, Jean-Claude Belfiore
In this paper we introduce a new right preprocessing method for the decoding of 2x2 algebraic STBCs, called algebraic reduction, which exploits the multiplicative structure of the…
DMT of weighted Parallel Channels: Application to Broadcast Channel
Lina Mroueh, Stéphanie Rouquette-Léveil, Ghaya Rekaya-Ben Othman +1
In a broadcast channel with random packet arrival and transmission queues, the stability of the system is achieved by maximizing a weighted sum rate capacity with suitable weights…
Golden Space-Time Block Coded Modulation
L. Luzzi, G. Rekaya-Ben Othman, J. -C. Belfiore +1
In this paper we present a block coded modulation scheme for a 2 x 2 MIMO system over slow fading channels, where the inner code is the Golden Code. The scheme is based on a set pa…
Distributed Space Time Codes for the Amplify-and-Forward Multiple-Access Relay Channel
Maya Badr, Jean-Claude Belfiore
In this work, we present a construction of a family of space-time block codes for a Multi-Access Amplify-and- Forward Relay channel with two users and a single half-duplex relay. I…
Distributed Space-Time Block Codes for the MIMO Multiple Access Channel
Maya Badr, Jean-Claude Belfiore
In this work, the Multiple transmit antennas Multiple Access Channel is considered. A construction of a family of distributed space-time codes for this channel is proposed. No Chan…
