Abstract:
1. A method of decoding a pulse signal modulated through a transmitted reference modulation scheme, the modulated pulse signal having successive pulse repetition periods, each pulse repetition period comprising a reference pulse followed by an information pulse delayed with a delay selected from a first and a second delay different from the first delay, the reference pulse having a reference point at a reference time instant of a pulse repetition period, the method comprising: adding to the modulated pulse signal, a first version of the modulated pulse signal respectively delayed with the second delay, and subtracting from the modulated pulse signal, a second version of the modulated pulse signal respectively delayed with a third delay equal to the second delay minus the first delay for obtaining a processed signal based upon the transmitted reference modulation scheme; and performing a non-coherent detection on the processed signal to provide a result to be analyzed within a time window centered with a second time instant delayed from the reference time instant by the second delay.
