| 中文摘要 | in this paper, an efficient iterative discrete fourier transform (dft) -based channel estimator with good performance for multiple-input and multiple-output orthogonal frequency division multiplexing (mimo-ofdm) systems such as ieee 802.11n which retain some sub-carriers as null sub-carriers (or virtual carriers) is proposed. in order to eliminate the mean-square error (mse) floor effect existed in conventional dft-based channel estimators, we proposed a low-complexity method to detect the significant channel impulse response (cir) taps, which neither need any statistical channel information nor a predetermined threshold value. analysis and simulation results show that the proposed method has much better performance than conventional dft-based channel estimators and without mse floor effect. |
