Characterization of effective capacity in AF relay systems

In this paper, effective capacity in amplify-and-forward (AF) relaying system is studied. For this purpose, a closed-form solution for the effective capacity of AF relays with a near optimal power allocation is extracted.

Duality and Capacity Region of AF Relay MAC and BC

We consider multi-hop multiple access (MAC) and broadcast channels (BC) where communication takes place with the assistance of relays that amplify and forward (AF) their received signals. For a two hop parallel AF relay MAC, assuming a sum power constraint across all relays we characterize optimal relay amplification factors and the resulting capacity regions. We find the sum rate capacity and ...

SNR Maximization at CSI Aware AF Relay

This paper concerns two-hop communication over relay-assisted Block fading channel. It is assumed there is not a direct link between the transmitter and the affiliated destination and the communication occurs in two hops through the use of a relay, where the amplify and forward (AF) strategy is employed at this node. In this case, in a Rayleigh block fading channel, the optimal weight function ...

Reduced Energy Consumption in Multi-Hop MIMO-AF Relay Systems

Energy consumption is an important performance indicator for ensuring both the economical and environmental sustainability of the next generation communication networks. Co-operative communication is an effective way of improving the communication system performances. In the proposed system, the energy consumption is reduced by means of reducing the BER in MIMO-AF systems. The total transmissio...

Power allocation and effective capacity of AF successive relays

In the relay based telecommunications with K relays between the source and destination, K +1 time or frequency slots are required for a single frame transmission. However, without the relays, only one time or frequency slot is used for a single frame transmission. Therefore, despite the benefits of relaying systems, this type of communications is not efficient from the spectral efficiency viewp...
