Abstract	In this study, the authors consider the communication scenario where two sources communicate with the help of a single relay, modelled as a half-duplex butterfly network. Closed-form expressions of the outage probabilities are derived in the high signal-to-noise ratio (SNR) regime for the orthogonal amplify-and-forward and non-orthogonal amplify-and-forward protocols. Then the expressions are approximated to enable power allocation. Closed-form power allocation schemes are proposed for each protocol, where only statistical channel knowledge is required. It is shown that the authors analyses match well with simulation results and the approximated versions are very close to the simulation results. The proposed power allocation schemes achieve a large SNR gain over the equal-power strategies and approach the optimal power allocation schemes.
