Estimation of Synchronization Parameters in AF Cooperative Networks

Nasir, Ali; Mehrpouyan, Hani; Blostein, Steven; Kennedy, Rodney; Durrani, Salman


In cooperative networks, multiple carrier frequency offsets (MCFOs) and multiple timing offsets (MTOs) originate due to multiple distributed nodes. In this paper, algorithms for joint estimation of these parameters and channels in amplify-and-forward (AF) relaying networks are proposed. A new training model and transceiver structure at the relays for achieving synchronization throughout the network is devised. New exact closed-form expressions for the Cramér-Rao lower bounds (CRLBs) for the...[Show more]
