Optimal incremental relaying in cooperative diversity systems
One of the main drawbacks of cooperative communication systems with half-duplex relaying is inefficient use of spectrum. Incremental relaying is an effective technique that overcomes this limitation. In this study, for a single-relay regenerative system, the authors propose a spectrally-efficient incremental relaying scheme that eliminates redundant relay transmissions such that the error propa...
متن کاملSelection metrics for multihop cooperative relaying
Cooperative relaying enables nodes to actively cooperate to deliver packets to their destination. The best-select protocol (BSP) implements a type of cooperative relaying that generalizes single path routing with sets of nodes (relay-sets) replacing the concept of a single node relay. Thus, while in traditional single path routing, packets hop from node to node, in BSP, packets hop from relay-s...

متن کاملPerformance Analysis of Selected Cooperative Relaying Techniques
Recently, cooperative communication has gained significant interest due to the fact that it exploits spatial diversity and provides capacity/performance gain over conventional singleinput single-output (SISO) systems. A mobile node with single antenna can cooperate with a nearby mobile node having single antenna in multi-user environment to create the effect of virtual multiple antenna system. ...
متن کاملCooperative Diversity Relaying Techniques in Wireless Communication Networks
In wireless networks, link budget can be relaxed by delivering the data using intermediate relay nodes. Although the immediate purpose of relaying is to obtain gain against path loss, it can also create spatial diversity due to the broadcast nature of the wireless medium. The objective of this work is to design and analyze relaying protocols that induce e2e cooperative diversity for ad hoc and ...
