Abstract:
A method of processing interference in a cellular communications system, in which system transmission and reception is carried out using TDMA channels in which a burst of one or more bits is transmitted per timeslot; the method comprising the steps of:carrying out frequency hopping on the TDMA channels of the system; for a given channel in a given cell of the communications system, determining a quality value per burst; identifying those bursts for which the quality value is below a predetermined threshold; determining a pattern of the identified bursts in terms of transmission frequency and time; calculating respective predicted patterns based on respective hopping determination parameters of other cells and of the given cell; comparing the determined pattern of the identified bursts with the predicted patterns; and responsive thereto predicting the hopping determination parameters of whichever interfering cell produced the determined pattern of the identified bursts by interfering with the given cell.
