Patent ID: 8842770

Claim:
A method of coding and decoding information conveyed by a pulse signal by a transceiver device, the method comprising: sending repetitively, from the transceiver, a reference pulse followed by a pulse train, the pulse train including at least a first information pulse delayed with respect to the reference pulse by a first delay and a second information pulse delayed with respect to the first information pulse by a second delay different from the first delay; and decoding a received pulse signal, at the transceiver device, by at least adding to the 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.
