A joint blind channel estimation and interference suppression scheme with efficient implementation for orthogonal frequency-division multiplexing (OFDM) systems is presented. In particular, an equalising filterbank is designed and the channel estimate from a lower bound of the filterbank output power is derived. The proposed scheme and exhibits low sensitivity to unknown narrowband interference. It compares favourably with a subspace blind channel estimator.
