Abstract	The orthogonal frequency division multiplexing (OFDM) transmission scheme equipped with multiple receive antennas increases robustness against frequency-selective fading and combats loss in SNR. Based on the multichannel signaling property, this letter develops a frequency-domain blind channel estimator for OFDM systems without cyclic prefix (CP). With high data efficiency and low computational complexity, the proposed algorithm is able to identify the channels using a single received OFDM data block. Numerical simulations show that the proposed method performs satisfactorily with only one or very few received OFDM blocks, as compared to the existing subspace-based methods which require many more data records.
