This paper derives the error probability of a two-way relay-based communication system with opportunistic selection in Rayleigh fading environments. We consider a two-way wireless communication system where two nodes, acting as sources, are unable to exchange data directly and, thus, proceed via L intermediate relay terminals. We investigate a single-relay selection scheme wherein only the best among...
We consider adaptive decode-and-forward (DF) cooperative-diversity system where a source node communicates with a destination node directly and indirectly (through multiple relays). In this paper, we analyze the system where N multiple relays that have the strongest signal strength at the destination are selected out of M relays and forward their received data from the source node to the destination...
Performance analysis of cooperative multiple-input multiple-output (MIMO) relaying system with a single relay is discussed in this paper. The MIMO scheme is based on Alamouti space-time block coding (STBC) over Rayleigh flat fading channels. The source node, equipped with two transmit antennas, simply broadcasts each STBC code to the relay and the destination nodes. Then, the relay node, equipped...
In this letter, we consider the adaptive decode-and-forward (DF) and amplify-and-forward (AF) cooperative-diversity systems with the Nth best-relay selection scheme. In the best-relay selection scheme, from the set of M relays the best relay only forwards the source signal to the destination. However, the best relay might be unavailable; hence we might resort to the second, third or generally the...
