39. The method of claim 38 wherein said grouping step comprises: comparing the temporary digital signatures of other potential unknown segments to a parametized potential unknown segment; for all potential unknown segments matched by a given temporary digital signature, temporally aligning the parametized signal information of said segments; and constructing a best fit to said aligned parametized signal information.
39. The method of claim 38 wherein said grouping step comprises: comparing the temporary digital signatures of other potential unknown segments to a parametized potential unknown segment; for all potential unknown segments matched by a given temporary digital signature, temporally aligning the parametized signal information of said segments; and constructing a best fit to said aligned parametized signal information. 40. The method of claim 39 wherein said step of constructing a best fit comprises polling each bit position of such aligned parametized signal information and assigning to the corresponding bit position of said best fit the value of the majority of parametized segments in said bit location.
