摘要：

This paper considers a multiuser two-way relay system with time division broadcast (TDBC) protocol, where multiple end-sources compete to exchange information with another end-source through the help of a single half-duplex amplify-and-forward (AF) relay. We derive a tight closed-form lower bound for the system outage probability over Nakagami-m fading channels with integer fading parameters. An asymptotic expression for the outage probability in high signal-to-noise ratio (SNR) regime is also obtained. Numerical results corroborate the theoretical analysis.
