Abstract: A receiver receives data from a sequence of OFDM symbols transmitted via a channel, each OFDM symbol comprising a plurality of data bearing sub-carriers and a plurality of pilot bearing sub-carriers. The receiver includes a channel estimator for estimating the channel and an equalizer for reducing the effects of the channel so that the data can be recovered from the received OFDM symbols. The channel estimator includes a notch processor which is arranged in operation to detect a notch in a received OFDM symbol, the notch providing a plurality of the sub-carriers of the received OFDM symbol within a frequency range which were not transmitted by the transmitter, to determine one or more missing pilot sub-carriers which would have been transmitted within the notch sub-carriers of OFDM symbols according to a pilot sub-carrier pattern, and to generate one or more replacement pilot data symbol for a missing pilot data sub-carrier.
