Abstract	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 estimation errors. Moreover, the influence of channel estimation errors on the bit-error performance of space-time block coding and modulation was simulated by the Monte Carlo method showing that the losses of the performance caused by the channel estimation errors within the above Cramer-Rao bound are the minima in the losses of bit-error performance caused by all the channel estimation errors. This conclusion accorded with the analytical result in theory.
