Le relais de sélection est une technique prometteuse pour la mise en œuvre pratique de systèmes coopératifs avec plusieurs nœuds relais. Cependant, pour sélectionner le meilleur relais, une connaissance globale des canaux est requise au niveau de l'entité de sélection, ce qui peut entraîner une surcharge de signalisation considérable. Dans cet article, nous considérons le problème de sélection de relais dans les systèmes de communication à double saut avec amplification et transmission (AF) avec informations partielles sur l'état du canal (CSI). Des stratégies de sélection de relais visant à minimiser soit la probabilité de panne, soit le taux d'erreur binaire (BER) avec des CSI quantifiés disponibles sont présentées. Nous proposons également un quantificateur basé sur le débit cible pour partitionner efficacement la plage SNR pour une sélection de relais minimisée en cas de panne, et un quantificateur basé sur le BER cible pour une sélection de relais minimisée par BER. Les résultats de la simulation montrent que des performances quasi optimales peuvent être obtenues avec un retour de quelques bits à l'entité de sélection.

Abstract: Selection relaying is a promising technique for practical implementation of cooperative systems with multiple relay nodes. However, to select the best relay, global channel knowledge is required at the selecting entity, which may result in considerable signaling overhead. In this paper, we consider the relay selection problem in dual-hop amplify-and-forward (AF) communication systems with partial channel state information (CSI). Relay selection strategies aiming at minimizing either the outage probability or the bit error rate (BER) with quantized CSI available are presented. We also propose a target rate based quantizer to efficiently partition the SNR range for outage minimized relay selection, and a target BER based quantizer for BER minimized relay selection. Simulation results show that near optimal performance is achievable with a few bits feedback to the selecting entity.

AB - Selection relaying is a promising technique for practical implementation of cooperative systems with multiple relay nodes. However, to select the best relay, global channel knowledge is required at the selecting entity, which may result in considerable signaling overhead. In this paper, we consider the relay selection problem in dual-hop amplify-and-forward (AF) communication systems with partial channel state information (CSI). Relay selection strategies aiming at minimizing either the outage probability or the bit error rate (BER) with quantized CSI available are presented. We also propose a target rate based quantizer to efficiently partition the SNR range for outage minimized relay selection, and a target BER based quantizer for BER minimized relay selection. Simulation results show that near optimal performance is achievable with a few bits feedback to the selecting entity.
