PARAMETER ESTIMATION TECHNIQUES APPLICABLE TO MULTI-SIGNAL COMMUNICATIONS MEDIA

Systems and methods for determining the spectral arrangement of a composite signal that includes a plurality of individual signals, so that one or more individual signals may be separated from the composite signal. According to one embodiment, a first set of samples are taken from the composite signal during a first time duration, and a second set of samples are taken from the composite signal during a second time duration. The first and second time durations are selected such that at least a portion of the second time duration does not temporally overlap the first time duration. A weighing function is applied to the first and second sets of samples to generate weighted sample sets. The autocorrelation between the first and second weighted sample sets is measured, thereby providing information about the bandwidth occupancies of each of a plurality of individual signals within the bandwidth of the composite signal.
