Nada Ebaid, Mona Shokair, Sami A. El Dolil . Performance Enhancement of Cooperative Cognitive Relay Network using Multi Antennas Multi Hopping Techniques. International Journal of Computer Applications. 144, 9 ( Jun 2016), 18-22. DOI=10.5120/ijca2016910430
In this paper, two systems will be introduced to improve the performance of Cooperative Cognitive Relay Network (CCRN). The first is Compress-and-Forward (CF) relay scheme based on joint source-channel coding for three-terminal classical relay network. Simulation results show that CF relay scheme gives remarkable performance gains over other cooperation strategies such as decode-and-forward and amplify-and-forward in this scenario where both source-relay and relay destination links have low signal-to-noise ratios. The second system is multi-hopping cooperative relaying with multi-antennas using decode and forward scheme. Using multi-hopping with multi-antennas techniques in CCRN gives a remarkable enhancement in the performance than using only one hop with single antenna system.
