Impact of unknown time-varying fading on the information rates of amplify and forward cooperative systems

Mohammadi, Mohammadali; Sadeghi, Parastoo; Lamahewa, Tharaka; Ardebilipour, Mehrdad


We study information rate penalties for single-relay amplify and forward (AF) cooperative communication in the presence of unknown and time-varying fading. The penalty is defined as the gap between the information rate with perfect channel state information and that when the source-destination, source-relay and relay-destination channels are unknown at the receiving nodes. We prove that this gap in the cooperative system is the sum of gaps in the source-destination (single-hop) and...[Show more]
