| 摘 要： | A subspace-based blind channel estimation algorithm for MIMO-OFDM systems is proposed. This algorithm exploits the eyclostationarity introduced by cyclic prefix of OFDM to estimate the channel parameters. The proposed new algorithm is found to be outperforming the other algorithm with respect to convergence rate and achievable mean square error and robustness to channel order over determination.

| Abstract: | A subspace\|based blind channel estimation algorithm for MIMO\|OFDM systems is proposed. This algorithm exploits the cyclostationarity introduced by cyclic prefix of OFDM to estimate the channel parameters. The proposed new algorithm is found to be outperforming the other algorithm with respect to convergence rate and achievable mean square error and robustness to channel order over determination. |
