Systems and methods are disclosed for processing at least two spread spectrum signals that at least partially overlap in time and in frequency. A main correlator bank with a trip detection component can determine a PN code phase for each of the spread spectrum signals that are associated with a PN code signal. The signals may at least partially overlap in time and in frequency. The PN code phases can be determined by comparing the signals to internally generated PN code phases. Based on the comparison, trips associated with the code phases are detected. The PN code phase for each signal can be used to extract a data signal from the signal. The data signals can be outputted.
