  1. Improving Amplify-and-Forward Relay Networks Optimal Power Allocation versus Selection By: Yi Zhao, Raviraj Adve and Teng Joon Lim Presentation by: Amir Minayi Jalil

  2. Theorem 1: In the high SNR regime, the outage probability of AP-AF scheme can be bounded as

  3. Proof for upper bound :

  4. So an upper bound can be introduced:

  5. Since α0 is exponentially distributed variable with parameter λ0, we have: x’ = 1 − x/δ

  6. We know: • λ0, λiand ξithe exponential distribution parameters of the Rayleigh channel amplitude squares: α0, αiand βi

  7. For the lower bound (AP):

  8. Lower bound

  9. SELECTION AMPLIFY-AND-FORWARD SCHEME (Outage Analysis)
