Opportunistic Relaying in Time Division Broadcast Protocol With Incremental Relaying
In this paper, the authors investigate the performance of Time Division BroadCast protocol (TDBC) with Incremental Relaying (IR) when there are multiple available relays. Opportunistic Relaying (OR), i.e., the "Best" relay is select for transmission to minimize the system's outage probability, is proposed. Two OR schemes are presented. The first scheme, termed TDBC-OIR-I, selects the "Best" relay from the set of relays that can decode both flows of signal from the two sources successfully. The second one, termed TDBC-OIR-II, selects two "Best" relays from two respective sets of relays that can decode successfully each flow of signal.
