“Amplify and Forward” and “Decode and Forward” are the two main relaying functions that have been proposed since the advent of cooperative communication. “Soft Decode and Forward” is a recently introduced relaying principle that is to combine the benefits of the classical two relaying algorithms. In this work, we thoroughly investigate soft relaying algorithms when convolutional or turbo codes ...

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...

An opportunistic relay selection based on instantaneous knowledge of channels is considered to increase security against eavesdroppers. The closed-form expressions are derived for the average secrecy rates and the outage probability when the cooperative networks use Decode-and-Forward (DF) or Amplifyand-Forward (AF) strategy. These techniques are demonstrated analytically and with simulation re...

We apply non-binary channel coding to the symmetric multi-carrier two-way relay channel and evaluate two decoding approaches at the relay. Complete-decode-and-forward (CDF) decodes the packets of both users before forwarding the binary sum in the second phase, while functional-decode-andforward (FDF) directly decodes the binary sum of both packets. For both approaches, we study suitable subchan...
