Abstract
This comment first shows that the Cramér-Rao lower bound (CRLB) derivations in the above paper are not exact. In addition, contrary to the claims in the above paper, the assumptions of perfect timing offset estimation and matched-filtering at the relays affect the generality of the analytical results and cannot be justified.
