Abstract: In wireless network signal fading occurs due to multipath propagation. It can be mitigated through the use of diversity. Cooperative diversity is a form of spatial diversity that uses a collection of distributed antennas belonging to multiple terminals, each with its own information to transmit. The broadcast nature of wireless medium is the key property that allows for the cooperative diversity among the transmitting terminals. OSTBC with amplify and forward (AF) cooperation protocols can be deployed in a system with FD relaying. This offers predominant advantage of achieving high coding gain. Also the performance of the system can be improved with selecting the best relay based on its SNR.
