1. Coding Schemes for Relay Networks
Sammanfattning : 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. LÄS MER
2. Channel Estimation for Amplify and Forward Relay Networks
Sammanfattning : The use of intermediate-relaying nodes has been identified as a promising technique for enhancing coverage and combating the impairments of Multiple-Input-Multiple-Output (MIMO) wireless channels. The main ideais to introduce relays that forward the data to the destination which isotherwise out of the reach of the source. LÄS MER
3. Cooperative Strategies in Multi-Terminal Wireless Relay Networks
Sammanfattning : 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. LÄS MER
4. On the Benefits of Moving Relay Nodes in Wireless Networks
Sammanfattning : In order to meet the needs of high speed wireless connections, a new generation of cellular network, i.e., Long Term Evolution (LTE) has been standardized and deployed by the 3rd Generation Partnership Project (3GPP). By employing ad- vanced smart antenna techniques, fast channel dependent scheduling, adaptive coding and modulation, etc. LÄS MER
5. Moving Networks, a Better Way to Serve Vehicular Users
Sammanfattning : Nowadays, a great number of mobile broadband users are vehicular. It is very common that people are using their mobile devices either for working or entertainment when they are on the go. We are expecting mobile broadband to offer comparable experience everywhere, e.g. LÄS MER
