摘要：
This paper addresses pilot-aided multiuser least square (LS) channel estimation for the uplink of MIMO-OFDM systems. The systems under consideration allow all users use all available subcarriers independently and thus involve multiuser interference in the frequency domain. We develop the decentralized and centralized channel estimation algorithms according to different multiuser scenarios. Optimal multiuser pilots are proposed specially for centralized estimation methods with respect to the mean square error (MSE) of LS channel estimate.
