Abstract
We investigate the performance of pilot-aided channel estimation and data detection for multi-input multi-output (MIMO) systems. We analyze and compare the Cramer-Rao bound (CRB) on channel tap estimation error for different design models of the pilot sequences. Then, the minimum mean square error (MMSE) estimation method with deflation is performed for channel identification for the embedded pilot scheme.
