Abstract
Data-aided channel estimation based on maximum-likelihood criterion has recently been proposed for ultra-wideband communications. However, its performances was evaluated by using only numerical simulation. This letter derives the Cramer-Rao lower bound for the method and verifies the analytical results via a numerical example.
