  • Signal processing device and method, radiofrequency transmission system including such a device
    Patent number: 8467744
    Abstract: A device for processing a signal carrying information to be transmitted using a radiofrequency signal, for transformation of the signal into two signals of identical amplitude phase-shifted respectively relative to the information-carrying signal according to two variable and opposing phase shifts. The device includes a mechanism transforming the information-carrying signal. The device transforms the information-carrying signal into two signals of constant amplitude and of variable phase shifts according to values of the information-carrying signal, for as long as the amplitude of the information-carrying signal is greater than a predetermined value, and transforms the information-carrying signal into two signals of variable amplitude according to the values of the information-carrying signal, when the amplitude of the information-carrying signal is less than the predetermined value.
