Abstract
The invention relates to a method of resolving collisions between at a receiver, and also to such a receiver. According to the invention, the method performed by the receiver processes the signal representative of a collision. The method consists in particular in selecting signal “fingers” having a power level greater than a threshold value, and in combining said fingers with one another to find configurations for which the packets that result from the combination are error-free, thereby enabling the transmitters from which the colliding packets originated to be identified.
