Dual hop wireless communications over Nakagami fading

We study the performance of dual-hop wireless communications systems with non-regenerative relays over Nakagami-m fading channels. Deriving tight upper bounds for the end-to-end SNR, important performance criteria such as average end-to-end SNR and error probability are studied. Numerical and computer simulations results are presented to verify the accuracy of the proposed mathematical analysis and to compare our results with previously published ones.
