Cooperative space-time codes with network coding [PDF]
Because of the gains like diversity, throughput, and the coverage extension provided by the multiple-input multiple-out (MIMO) systems, it has been part of the various wireless communications standards. However, to reap the benefits offered by MIMO systems in size-constrained nodes, used in wireless communications, has been a challenging issue.

MBMS with User Cooperation and Network Coding [PDF]
In this paper user cooperation with network coding is applied to MBMS (Multimedia broadcast/multicast service) where Raptor codes are currently used. User cooperation together with network coding is used to save bandwidth and improve user perceived QoS for broadcast/multicast services in the future mobile communication networks.

Network Coding Techniques in Cooperative Cognitive Networks [PDF]
In this paper, we investigate transmission techniques for a fundamental cooperative cognitive radio network, i.e., a radio system where a Secondary user may act as relay for messages sent by the Primary user, hence offering performance improvement of Primary user transmissions, while at the same time obtaining more transmission opportunities for its ...

Network coded cooperation in delay tolerant networks
Implementation of network coding (NC) is expanding to a diverse set of networks due to the flexible design provided through its use, enabling a trade-off between robustness and spectral efficiency. In this paper, we investigate the application of NC in delay tolerant networks (DTN) through the use of software defined radio (SDR) nodes.

LLR-based coded performance analysis of cognitive dual-hop BICM systems
In this work, we analyze the performance of a cooperative two-hop cognitive relaying system using the “detect-and-forward” strategy. The cooperation between secondary users, in the underlay spectrum sharing mode, is under an interference constraint ...

Coded Caching for Broadcast Networks with User Cooperation
Caching technique is a promising approach to reduce the heavy traffic load and improve user latency experience for the Internet of Things (IoT). In this paper, by exploiting edge cache resources and communication opportunities in device-to-device (D2D) networks and broadcast networks, two novel coded caching schemes are proposed that greatly reduce ...
