Cooperative space-time coding for wireless networks

Proceedings 2003 IEEE Information Theory Workshop (Cat. No.03EX674), 2004
We consider a cooperative system in which the partnering mobiles are equipped with multiple antennas. We present space-time codes that have the capability of providing full cooperation diversity, while achieving maximum possible diversity and best performance in the inter-user channel.

Cooperative coding on orthogonal information networks

2009
The focus of this thesis is on communication over cooperative information networks. In the first half of the thesis, we consider lossy source coding problems where a relay assists in the communication of a source stream between two terminals. The following two configurations are studied – (1) The Slepian-Wolf problem setup when the two encoding ...

Cooperative communication with network coding

2012 IEEE 16th International Symposium on Consumer Electronics, 2012
In cooperative communication system, mobile users are constantly transmitting and relaying data. On the other hand, network coding has been widely investigated in communication system. In this paper, we aim to combine network coding with the conventional cooperative communication system, however, we face certain problems.

Incremental Network Coding in Cooperative Transmission Wireless Networks

2008 IEEE 68th Vehicular Technology Conference, 2008
For block-fading Rayleigh channels, this work considers a network coding approach to cooperative transmission. The network under consideration consists of two sources, S and P, that transmit to a common destination, D. Using half-duplex channels, S and P transmit their packets to D; they also overhear each other's transmission.

Cooperative network coding

2011
This chapter provides a detailed description of using network coding in cooperative relay networks as well as a practical network spread coding scheme for cooperative communications in multipath fading channels. The concept of Network coding (NC), however, differs from simple network routing due to the fact that NC aims at whole network optimization ...

Cooperative relaying in Wi-Fi networks with network coding

IEEE Wireless Communications, 2012
Recently, network coding has emerged as a new cooperative technique for improving network throughputs over traditional routing techniques. Network coding allows intermediate nodes to combine packets using an algebraic function before forwarding. Selfless cooperation by the intermediate nodes is thus implicitly assumed in the network employing network ...

On the potential of network coding for cooperative awareness in vehicular networks

2015 IEEE 2nd World Forum on Internet of Things (WF-IoT), 2015
Vehicular active safety applications require the continuous exchange of positioning and basic status information between neighboring vehicles. This exchange is based on the periodic transmission/reception of 1-hop broadcast messages on the control channel.

Cooperative Network Coding for Wireless Ad-Hoc Networks

IEEE GLOBECOM 2007-2007 IEEE Global Telecommunications Conference, 2007
In wireless ad-hoc networks, a major challenge is how to provide robust and efficient communication. To achieve this goal, cooperative communication and network coding have been proven to be effective. In the literature, most existing studies focus on the performance of the two schemes separately.

On Network Codes for Multiuser Cooperative Communication in a Line Network

2013 IEEE 77th Vehicular Technology Conference (VTC Spring), 2013
In this paper, the use of network coding is exploited to improve the cooperative diversity order of multi-source multi-hop networks with line topology. We elaborate on a previous system model by allowing user nodes to be arbitrarily located along the line network, to have the ability to perform network decoding, and to be able to listen to upstream ...
