identify strong disturbers affecting their neighbors in the group fig1 illustrates a schematic diagram of a simplified binder comprising eleven lines and the interference relationship between these eleven different lines included in that binder the arrows used in this fig indicate the interference induced by one line onto the other given the interference relationship as shown in this fig according to an embodiment of the present invention two interference groups are identified a first interference group id 1 to which lines 1 2 3 4 and 5 belong and a second interference group id 2 to which lines 6 7 9 and 10 belong the association of lines 8 and 11 either to the second group or to yet another group may depend on the level of the interference experienced by these lines if they are subjected to a high level of interference they will be associated according to this example with the second interference group otherwise they will each constitute an interference group of their own in other words in the latter case the binder will include two additional interference groups a third interference group id 3 will include line 8 and a forth interference group id 4 will include line 11 as may be seen from this figure it may very well be that.
