Adaptive Modulation for Opportunistic Decode-and-Forward Relaying

IEEE Transactions on Wireless Communications, 2011
Orthogonal 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.

Decode-and-Forward Cooperative Networks with Relay Selection

2007 IEEE 66th Vehicular Technology Conference, 2007
In 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, 2010
In 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), 2013
In 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, 2007
We 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 ...
