Cramer-Rao Bounds for Channel Estimation in Amplify-and-Forward Cooperative Communication Systems
The Cramér-Rao bounds of centralized and distributed channel estimations are studied for the cooperative communication systems with single amplify-and-forward relay and two transmission phases. Particularly, two cooperation protocols are considered with full cooperation in both transmission phases and partial cooperation in the listening phase, respectively. It is shown that centralized channel estimation is a better choice than distributed channel estimation for both full and partial cooperation protocols.
