Outage Probability of Two-Way Amplify-and-Forward Relaying Over Nakagami-m Fading Channels

The outage probability of a two-way amplify-and-forward relay system over independent and non-identical Nakagami-m fading channels is investigated. The arbitrary transmit powers at transceivers and relay are considered, and a generalized closed-form expression for the outage probability of the system is derived. Finally, numerical simulations are used to verify the tightness of the analytical result.
