2. 1. Cooperative Communications : Link Reliability and Power Efficiency

   Author : Tafzeel ur Rehman Ahsin; Ben Slimane; Xavier Lagrange; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cooperative Communications; Link Reliability; Power Efficiency; Energy Efficiency; Network Coding; Cooperative Relaying; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Abstract : Demand for high data rates is increasing rapidly for the future wireless generations, due to the requirement ofubiquitous coverage for wireless broadband services. More base stations are needed to deliver these services, in order tocope with the increased capacity demand and inherent unreliable nature of wireless medium. READ MORE

4. 2. Smart Cooperation with Network Coding in Hierarchical Wireless Networks

   Author : Nan Li; Lars Kildehöj Rasmussen; Daniel Lucani; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless communications; Hierarchical networks; 5G; Cognitive radio; Internet of Things; Cooperative communications; Spectrum sharing; Network coding; Optimization; Performance analysis.; Electrical Engineering; Elektro- och systemteknik;

   Abstract : To achieve more dynamic, efficient and intelligent use of the scarce wireless spectrum resource, the concept of cooperation has been formalized into several hierarchical network models in future mobile networks. Cooperative communications, such as relaying, can potentially increase communication efficiency and spectrum utilization due to the broadcast nature of wireless networks, and may lead to a better support for diverse communication modes with flexible spectrum sharing.

5. 3. Cooperative Strategies in Multi-Terminal Wireless Relay Networks

   Author : Jinfeng Du; Mikael Skoglund; Ming Xiao; Lizhong Zheng; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cooperative communication; relay; network coding; network information theory; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Abstract : Smart phones and tablet computers have greatly boosted the demand for services via wireless access points, keeping constant pressure on the network providers to deliver vast amounts of data over the wireless infrastructure. To enlarge coverage and enhance throughput, relaying has been adopted in the new generation of wireless communication systems, such as in the Long-Term Evolution Advanced standard,  and will continue to play an important role in the next generation wireless infrastructure.

6. 4. Link Reliability in Cooperative Relaying Using Network Coding

   Author : Tafzeel ur Rehman Ahsin; Slimane Ben Slimane; Ove Edfors; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cooperative Communications; Network Coding; Multiple Access Relay Channel; Telecommunication; Telekommunikation; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Abstract : Demand for high data rates is increasing rapidly for future wireless systems.This trend is due to the increase in the number of mobile subscribers that need bandwidth hungry multimedia applications anywhere, anytime. Fourth generation cellular systems like IMT-advanced are being developed to meet these requirements. READ MORE

7. 5. Coding Schemes for Relay Networks

   Author : Majid Nasiri Khormuji; Mikael Skoglund; Gerhard Kramer; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Relay networks; capacity; decode-and-forward; amplify-andforward; compress-and-forward; nonlinear relaying; noisy network coding; hybrid relaying; Telecommunication; Telekommunikation;

   Abstract : Cooperative communications by pooling available resources—for example, power and bandwidth—across the network, is a distributed solution for providing robust wireless transmission. Motivated by contemporary applications in multi-hop transmission and ad hoc networks, the classical three-node relay channel (RC) consisting of a source–destination pair and a relay node has received a renewed attention.
