On the Outage and Error Probability of Amplify-And-Forward Multi-Hop Diversity Transmission Systems
Golnaz Farhadi, Norman C. Beaulieu · 2008
Simple, closed-form expressions for the outage probability and bit error rate of multi-hop diversity transmission systems employing either fixed or selective amplify-and-forward relaying are derived. Numerical results show the accuracy of the obtained analytical results for sufficiently large values of signal- to-noise ratio. In addition, it is shown that a multi-hop diversity transmission system employing fixed amplify-and-forward relaying outperforms the corresponding systems employing fixed decode-and-forward, selective decode-and-forward or selective amplify-and-forward relaying, despite the noise amplification at all relays.
