Abstract
A method comprises: receiving colliding signals by a receiver from a plurality of signal sources, such that the receiver has a respective non-zero probability of detecting and identifying the colliding signals from each respective one of the signal sources at a given time. The colliding signals are configured with at least one common transmission parameter value so as to interfere with each other, so that the receiver only detects and identifies one of the received colliding signals at any given time. The receiving and identifying are performed during each of a plurality of cycles. A probabilistic model is used to calculate the location of the receiver. The model correlates a respective number of times the receiver detects and identifies one of the colliding signals and the probability of that signal being identified by the receiver, given the location of the receiver.
