A method and devices are provided for estimating a signal received at a wireless communication cell along a communication channel where the transmission/reception frequency used for conveying traffic along that communication channel is substantially equal to transmission/reception frequency used for conveying traffic along at least one other communication channel extending from/to at least one substantially interfering cell. The method comprises: associating a pilot sequence with the wireless communication cells operative in the wireless network; providing a receiver with information that would allow estimation of the pilot sequence used by a transmitter with which that receiver is adapted to communicate; providing the receiver with information that would allow estimation of the 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, e.g. by means of correlation; subtracting the estimated signal from an input signal received by that receiver; and estimating the pilot signal associated with a pilot sequence used by one or more of the other transmitters; carrying out a modified estimation of the pilot signal used by the first transmitter.
