Dynamic Decode and Forward with Network Coding
2012 IEEE 75th Vehicular Technology Conference (VTC Spring), 2012This paper is divided into two parts. In the first part, we analyze outage probability of dynamic decode and forward (DDF) with network coding (NC) and compare outage probability with using NC and without using NC. In the second part, we use MATLAB programming language to simulate our system model.

Decode-and-forward strategies for bidirectional relaying
2008 IEEE 19th International Symposium on Personal, Indoor and Mobile Radio Communications, 2008We consider a three-node network, where a relay node establishes a bidirectional communication between two nodes using a two-phase decode-and-forward protocol. In the first phase the two nodes transmit their messages to the relay node which decodes them.

A New Incomplete Decode-and-Forward Protocol
2008 IEEE Wireless Communications and Networking Conference, 2008In this work, we explore the introduction of distributed space-time codes in decode-and-forward (DF) protocols. We propose a new Incomplete DF protocol, based on a partial decoding at the relays. This strategy allows the new protocol to bring both full diversity and full symbol rate.

Bounding of MAP decode and forward relaying
2010 IEEE International Symposium on Information Theory, 2010We formulate the maximum a posteriori (MAP) rule for the decode-and-forward transmission strategy operating with a noisy relay. From the MAP rule we derive an analytical bound on the error probability, taking into account decoding errors at the relay.

Decode‐and‐forward with full‐duplex relaying
International Journal of Communication Systems, 2011SUMMARYThis paper addresses the full‐duplex relaying. Some expressions for outage and average capacity of a two‐hop cooperative system with a full‐duplex relay are derived under an independent but not identically distributed Rayleigh fading environment. Using these expressions, we provide the performance analysis without Monte Carlo simulations.

Cooperative Fading Regions for Decode and Forward Relaying
IEEE Transactions on Information Theory, 2008Cooperative transmission protocols over fading channels are based on a number of relaying nodes to form virtual multi-antenna transmissions. Diversity provided by these techniques has been widely analyzed for the Rayleigh fading case. However, short range or fixed wireless communications often experience propagation environments where the fading ...

Decode-and-Forward Cooperative Networks with Relay Selection
2007 IEEE 66th Vehicular Technology Conference, 2007In this paper, we focus on the decode-and-forward (DF) cooperative networks with relay selection. Many detection schemes have been proposed for the DF; but it has been shown that the cooperative maximum ratio combining (C-MRC) can achieve almost the same performance as the optimum maximum likelihood detector and has a much lower complexity.

Outage analysis of opportunistic decode-and-forward relaying
2010 7th International Symposium on Wireless Communication Systems, 2010In this paper, we investigate a dual-hop opportunistic decode-and-forward relaying scheme where the source may or not be able to communicate directly with the destination. We first derive statistics based on exact probability density function (PDF) of each hop.

Opportunistic Decode-and-Forward Relaying with Interferences at Relays
Wireless Personal Communications, 2011In this paper, a decode-and-forward cooperative interference-limited multiple relay network is considered. An efficient relay selection strategy and its performance analysis are proposed, where only the relay nodes are affected by multiple interferences.

Adaptive Modulation for Opportunistic Decode-and-Forward Relaying
IEEE Transactions on Wireless Communications, 2011Orthogonal relay based cooperative communication enjoys distributed spatial diversity gain at the price of spectral efficiency. This work aims at improving the spectral efficiency for orthogonal opportunistic decode-and-forward (DF) relaying through employment of novel adaptive modulation scheme.
