Abstract

This study deals with the performance analysis of time division broadcast (TDBC) protocol with channel estimation errors. The tight lower bounds for individual and system outage probabilities are first presented in closed-form. It is shown that the presence of channel estimation error causes outage probability to maintain a fixed level even when a noiseless channel is adopted. Simulation results validate the accuracy of our analytical results. Furthermore, comparison of signal-to-noise ratio (SNR) gap ratio shows that TDBC protocol is less sensitive to the effect of channel estimate error than analog network coding (ANC) protocol.
