  In this paper, we investigate the outage performance of time division
broadcasting (TDBC) protocol in independent but non-identical Rayleigh
flat-fading channels, where all nodes are interfered by a finite number of
co-channel interferers. We assume that the relay operates in the
amplified-and-forward mode. A tight lower bound as well as the asymptotic
expression of the outage probability is obtained in closed-form. Through both
theoretic analyses and simulation results, we show that the achievable
diversity of TDBC protocol is zero in the interference-limited scenario.
Moreover, we study the impacts of interference power, number of interferers and
relay placement on the outage probability. Finally, the correctness of our
analytic results is validated via computer simulations.
