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. %K MIMO-OFDM %K Pilot-assisted channel estimation %K LS %K LMMSE %K Low-Bound of MSE
