Abstract
Demonstrates that the complex peak patterns generated by the correlation of truncated or augmented codes contains information about the modification of the code and that it is possible to retrieve that information by applying specific processing methods. Four processing methods are proposed. The first method extracts information from the peak patterns generated by the autocorrelation of the modified signal. The second method uses the cross-correlation of the modified signal with the original signal while the third method deals with the cross-correlation of the modified code with a test code that has the same length as the modified code. The fourth method allows the determination of the initial fill of truncated codes when the signal-to-noise ratio is sufficiently good.
