Cramer-Rao bound for channel estimation errors in space-time coding and modulation

A simple model for analysing channel estimation errors in space-time coding and modulation was constructed, and the Cramer-Rao bound expression for channel estimation errors was derived. It was also proved that the Cramer-Rao bound derived in the paper was a general and tight bound, as compared with the one given in the reported results of channel… CONTINUE READING
