This disclosure provides a system and method for separating a first signal from a second signal of a plurality of constituent signals within a composite signal. The method can include receiving a first portion of the composite signal at a first clock rate and exponentiating it to detect the first signal and the second signal within the composite signal and determine modulation estimates of the first and second signals and at least one symbol rate. The method can also include resampling the first portion based on the modulation estimates at x-times the at least one symbol rate to determine symbol trajectory, modulation type, and offset information between the first signal and the second signal. The method can include determining a synthesized first signal and a synthesized second signal representing the first signal and the second signal within the first period of time at a second clock rate that is a multiple of the first clock rate.
