PROJECT TITLE :
Jamming in Dual-Hop Amplify-and-Forward Relaying
The performance of a dual-hop amplify-and-forward (AF) relaying system in the presence of a jammer is analyzed by obtaining the end-to-end outage likelihood for the scenario where the system is interference restricted and operates in either Nakagami-zero.five or Rayleigh fading environments. Then, the optimal power allocation and transmission toward the relay and the destination for maximizing the outage likelihood is analyzed. It is shown that for both fading environments when the jammer power is sufficiently massive, jamming the relay and therefore the destination with equal power allocation is optimal, whereas when the jamming power is low, more power ought to be allocated to jam any of the supply–relay and relay–destination links having lower receiving signal power. In addition, the difference between the optimal and also the equal power allocation performance is investigated. Analytical results are verified and illustrated by some numerical results and simulations.
