Cooperative relay technology has recently been introduced into cognitive radio (CR)
networks to enhance the network capacity, scalability, and reliability of end-to-end …

In this tutorial, we have focused on the design of binary self-concatenated coding schemes
with the help of EXtrinsic Information Transfer (EXIT) charts and Union bound analysis. The …

Cooperative devices and mechanisms are increasingly important to enhance the
performance of wireless communications and networks, with their ability to decrease power …

In this paper, we propose a relay assisted multiuser Multiple-input multiple-output wireless
communication using multilayer space time block coding in the presence of Rayleigh fading …

The authors perform an outage probability analysis of a cooperative communication system
which transmits over multi‐path channels with best single, or best two relay pair selection …

In this paper, we investigate the spectrum sharing incentive to enhance the physical layer
security. The concept behind is that a legitimate source-destination pair, communicating in …

We propose to optimize a decode-and-forward (DF) cooperative relaying scheme with
Hybrid Automatic-Repeat-reQuest (HARQ) protocol for maximizing long-term average …

Mobile users with single antennas can still take advantage of spatial diversity through
repetition based cooperative transmission. In this paper, we consider a scheme in which the …

In this paper, performance of relay assisted wireless link is evaluated in the presence of
rayleigh fading where mobile handset is equipped with single transmit antenna, relay is …

This paper investigates the effect on performance for placing a decode and forward MIMO
relay at different position between source and destination for wireless uplink in the presence …
