Abstract :
In this correspondence, we introduce a new training protocol for channel state estimation in wireless relay networks. The distinctive feature of our protocol is that each relay forwards the imperfect channel state information (CSI) to the destination. We show that our method allows to obtain at the destination a higher effective SNR and a faster transfer of the CSI compared with the other existing training protocols.
