Optical relay system
WebThe system performance is studied in the context of dual-hop relay systems using mixed free-space optical/ radio frequency (FSO/RF) links. Two destinations need assistance from relay associated with FSO link connecting a source node. The heterodyne detection or direct detection is necessary for detecting signal in the first hop. In the second hop, the relay … WebJovan Stosic was born in Skopje on 28.02.1969.
