Abstract
(EN)
Systems, devices, and methods of the present invention facilitate secure communication by altering the set of symbol waveforms that may be in use in particular symbol times defined herein as Symbol Waveform Hopping. SWH may be enabled by selecting two or more modulation formats that have sufficiently comparable communication performance (e.g., occupied bandwidth and signal power efficiency), but characterized by symbol waveform alphabet that include different symbol waveform, so that the overall transmission/communication performance of the system is not significantly affected by switching between modulation formats. Some or all of the symbol waveforms in each alphabet may not be present in other alphabets.
(FR)
Les systèmes, dispositifs et procédés de la présente invention facilitent une communication sécurisée en modifiant l'ensemble de formes d'onde de symboles qui peut être utilisé dans des temps de symboles particuliers définis dans la description sous le terme de Saut de Formes d'onde de Symboles (SWH). Le SWH peut être activé en sélectionnant deux formats de modulation ou plus qui ont des performances de communication suffisamment comparables (par exemple, largeur de bande occupée et efficacité de la puissance du signal), mais caractérisés par un alphabet de formes d'onde de symboles qui comprend une forme d'onde de symboles différente, de telle sorte que les performances globales de transmission/communication du système ne sont pas affectées de manière significative lorsqu'on bascule entre des formats de modulation. Une partie ou la totalité des formes d'onde de symboles dans chaque alphabet peut ne pas être présente dans d'autres alphabets.
