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.

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.

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 ...

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.

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.

Decode-and-forward cooperation as the distributed encoding and decoding
2010 7th International Symposium on Wireless Communication Systems, 2010The decode-and-forward relaying is studied as two problems of the distributed encoding and decoding. Specifically, in the first problem, the source and the relay employ the same channel encoding, and the objective is to find how to distribute the decoding complexity between the relay and the destination.

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.

A Decode-and-Forward Scheme for Multihop Wireless Networks
2013 IEEE 78th Vehicular Technology Conference (VTC Fall), 2013In this paper, we propose a Decode-and-Forward (DF) relaying scheme for the multihop transmission in wireless networks, where the information generated by an independent source has to be sent to a far destination based on multiplerelay cooperation. The proposed DF scheme blends together convolutional channel coding with linear combination of blocks of ...

Cooperative Transmission Schemes for Decode-and-Forward Relaying
2007 IEEE 18th International Symposium on Personal, Indoor and Mobile Radio Communications, 2007We consider a low mobility cellular relaying system downlink where two mobile users are served by two neighboring decode-and-forward relays concurrently using the same frequency channel. We propose two cooperative relaying transmission schemes where each relay can choose proper precoding vectors based on its local channel knowledge to transmit data in ...
