The outage probability of dual-hop links with partial relay selection over Rayleigh fading channel in the presence of interferences is analysed. The outage expressions for amplify-and-forward (AF) and decode-and-forward (DF) relaying with relay selection, based on the instantaneous signal-to-interference ratio (SIR), are derived. Numerical results for both types of relays are presented and comp...

We propose a practical coding scheme for halfduplex estimate-and-forward relaying. The proposed construction is guided by the information theoretic coding scheme for the estimate-and-forward relay protocol. Our construction incorporates several design features to reduce receiver complexity without compromising performance. Observing that the relaying gain is significant only at low SNRs, we use...

We investigate the performance of adaptive decode-forward (ADF), amplify-forward (AF), and hybrid decode-amplify-forward (HDAF) relaying protocol. Specifically, we derive the closed-form expression of symbol error probability (SEP) for these three relaying protocols. For the AF protocol, we derive a simpler and more tractable final result than previously published work. Furthermore, analyzing t...

—Low-Voltage Powerline Communications (LV PLC) is a favorable information exchange scheme for many Smart Grid (SG) applications. In this paper we focus on the broadband dual-hop relaying systems over LV PLC channel in which the relay node operates in either Amplify-and-Forward (AF) or Decode-and-Forward (DF) relaying protocol. The closed-form expressions of capacities for non-cooperative and c...

In this paper, we present a novel hybrid automatic repeat request (HARQ) scheme for cooperative communication systems, called cooperative partial retransmission (CPR). The method is based on the retransmission of only a fraction of the original code word by the cooperating nodes. Based on the outage analysis, we derive the theoretical throughput expressions that are compared to numerical simula...
