  • The LMMSE channel estimation algorithms based on Pilot-Assisted is investigated for MIMO-OFDM systems,and the Low-Bound of MSE for LMMSE channel estimation is derived. A low rank channel estimator, at first, by using Singular Value Decomposition (SVD) is presented to reduce the complexity; Secondly, a simplified algorithm by using optimal pilot design is proposed. The simplified algorithm reduces not only the complexity evidently, but also attains the best estimation performance; Finally, The methods for estimating channel properties are developed.
