Abstract:
1. A system, comprising: a comparison component configured to compare a signal part group of a dual tone signal against a known signal set to produce a comparison result, where the signal part group is less than the signal; an identification component configured to perform an identification of a known signal that matches the dual tone through use of the comparison result, where the known signal is part of the known signal set; a construction component configured to construct a first error check window through use of the signal part group; an error component configured to make a determination when an error associated with the first error check window is not at a minimum, where the construction component is configured to construct a subsequent error check window after the determination is that the error associated with the first error check window is not at a minimum; an output component configured to cause an output that indicates the known signal that matches the dual tone signal when the error associated with the first error check window is at the minimum and configured to cause the output that indicates the known signal that matches the dual tone signal when the error associated with the subsequent error check window is at the minimum; and a processor configured to execute an instruction that relates to the comparison component, the identification component, the construction component, the error component, the output component, or a combination thereof.
