Abstract: A method and corresponding device for processing a frequency-modulated analog signal are disclosed. The signal includes a number of symbols belonging to a set of M symbols respectively associated with at least one frequency of a set of M frequencies. The method includes a phase of reading each symbol of the signal that includes a sampling of a signal portion corresponding to the duration of a symbol and delivering N samples (M being less than N). M individual discrete Fourier transform processing operations are performed on the N samples. Each individual processing operation is associated with each of the frequencies. The M individual processing operations deliver M processing results. The value of the symbol can be determined from the M processing results.

Abstract: A method for localizing an object, including the acts of: transmission of a first signal by a first transmitter assigned to the object and of a second signal by at least one second transmitter; reception of the first and of the second signal by at least three receivers; in each receiver and for the first and the second signal: a) generation of a first and of a second reference signal; b) correlation between the first signal and the first reference signal and between the second signal and the second reference signal; c) interpolation of samples resulting from the correlation; d) deduction of the propagation time of the first and of the second signal; e) calculation of the difference between the propagation times of the first and of the second signal; and, by triangulation, deduction of the position of the object.

Abstract: A contactless communication device is capable of communicating in a contactless way with a reader by using active load modulation. Each frame is preceded by a reception period. An antenna is configured to receive a reader signal during each reception period, and to receive a reader carrier signal and transmit a modulated device carrier signal to the reader during each frame. A processor is configured to carry out, in each reception period, a first synchronization between a signal originating from the reader signal received at the antenna and a device carrier clock signal device generated in the device. The processor is also configured to carry out, within each frame, a modulated device carrier signal suppression process in order to obtain a processed signal, and a second synchronization between the processed signal and the device carrier clock signal.
