摘要：
In this paper, a new semi-blind algorithm is presented for the estimation of Multiple-Input Multiple-Output (MIMO) Finite Impulse Response (FIR) channels. First, by using the MIMO linear prediction (LP), the whitening matrix is estimated blindly from the received data. The rotation matrix is then estimated by employing pilot symbols. The proposed method is validated through computer simulation-based experimentations, showing a high estimation accuracy as compared to the LS method in terms of the MSE of the channel estimate.
