A method is provided for estimating a signal received at a wireless cell along a channel where the frequency used for conveying traffic is substantially equal to frequency used for conveying traffic along at least one other channel extending from/to at least one substantially interfering cell. The method comprises: associating a pilot sequence with operative cells; providing a receiver with information to allow estimation of the pilot sequence by a respective transmitter; providing the receiver with information to allow estimation of pilot sequences associated with other transmitters communicating with other receivers located at the geographical proximity of that receiver; estimating the signal associated with the pilot sequence used by the first transmitter; subtracting the estimated signal from an input signal received by that receiver; estimating the pilot signal associated with a pilot sequence used by other transmitters; and modifying the estimation of the pilot signal used by the first transmitter.
