N2 - In this paper, we analyze the outage behavior of decode-and-forward relaying in the context of selective two-way
cooperative systems. First, a new relay selection metric is proposed to take into consideration both transmission rates
and instantaneous link conditions between cooperating nodes. Afterwards, the outage probability of the proposed
system is derived for Nakagami-m fading channels in the case when perfect channel state information is available
and then extended to the more realistic scenario where the available channel state information (CSI) is outdated
due to fast fading. New expressions for the outage probability are obtained, and the impact of imperfect CSI on
the performance is evaluated. Illustrative numerical results, Monte Carlo simulations, and comparisons with similar
approaches are presented to assess the accuracy of our analytical derivations and confirm the performance gain of
the proposed scheme.
