We consider a dual-hop amplify-and-forward relaying system where the channel state is unknown to both the transmitter and the receiver. Our objective is to derive the penalty of the information rate due to the unknown channel state information. We focus on determining the compound effects of fixed-gain relaying and unknown time-varying channels on the achievable information rates of the system. We show that penalty of the information rate due to the unknown channels decays with block length and...[Show more]
