  • Method and system for deinterleaving signals
    Patent number: 8102297
    Abstract: There are provided method and system for deinterleaving signals. The method comprises: (a) recording plural signal reception events, wherein each signal reception event is associated with a received signal at a receiver, and represented by a space-time coordinate having a space component based on a location of the receiver and a time component based on an arrival time of the received signal; (b) selecting a subset of signal reception events from the recorded signal reception events, wherein the number of signal reception events in the subset is based on the dimension of the space component; and (c) determining whether the signal reception events in the selected subset satisfy a predetermined condition, and if the determination is in the affirmative, associating the signal reception events in the selected subset with an emission of an emitter.
