Dual-hop transmissions with semi-blind relays over Nakagami-m fading channels

The performance of dual-hop wireless communication systems with semi-blind relays over Nakagami-m fading channels is investigated. The analysis is based on the evaluation of the average end-to-end signal-to-noise ratio. Some numerical plots show that the power imbalance between the hops may have both positive or negative effects on the overall system performance.
