Channel Estimation of MIMO-OFDM System Based on Subspace

摘要：

Blind channel identification and equalization methods of oversampled MIMO-OFDM systems based on subspace are discussed. The proposed method employs reducedrank orthogonal iteration to estimate noise subspace with low computational complexity. When the number of transmit antenna is greater than that of receive antenna of MIMO-OFDM system,oversampled method is used to obtain enough information for identification. Simulation results illustrate that the proposed method can achieve good performance.
