| Abstract | This letter offers a the statistical description of the basic two-hop Amplify-and-Forward link, where the relay node is selected based on an instantaneous and partial knowledge of the channel. In contrast with previous work, where relay selection requires global knowledge (2 hops) of the relaying link, the problem considered is interesting in practical ad-hoc systems, where only neighboring (1 hop) channel information is available to the nodes. The density probability function of the received signal-to-noise ratio for the considered relaying link is given in closed form, and an asymptotic approximation is proposed to simplify performance estimation. |
