Blind Channel Estimation For MIMO-OFDM System Based on Oblique Projection |
| |
| Abstract: | The blind channel estimation using oblique projection of MIMO-OFDM system is proposed in this paper. The condition and the proof of estimating the system are considered. The ambiguous matrix and computational complexity of this algorithm are discussed as well. The simulation results show the performance by normalized root mean square error and indicate the effectiveness of the proposed algorithm. |
