Abstract

Relay-based communication system enhances network capacity, transmission reliability and expands the coverage in wireless networks. This is a newly emerged area which has a lot of potential to support high data rate communication. Such wireless network operates in hostile environment where signal quality affected due to the presence of scatters in between communication link and they are responsible for the phenomena of shadowing and path-loss. Besides that, quality of signal also effected from multi-path fading phenomena, here constructive and destructive combining of signals occur at the receiver. It is quite challenging for the receiver to recover the original message correctly in presence of additive and multiplicative noise. Hence, for such type of network, a unified approach is required to attract researchers and resolved various unaddressed issues till now. In this paper, we will study dual-hop decode and forward serial relay network and establish a closed-form expression of outage probability for Nakagami-m fading channel.
