Patents by Inventor Julien Eyries

Julien Eyries has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method for estimating a carrier leak, an estimator and modulation system provided with automatic control of a carrier using said system
    Patent number: 7129802
    Abstract: The invention relates to a method of estimating a carrier leak making it possible to solve the accuracy degradation problem associated with a poor reception by the central carrier. A subject of said invention is a method of estimating a carrier leak consisting in: varying a complex gain Z applied to the received signal s between at least two predetermined values Z1 and Z2; measuring the position (PD1, PD2) of the central carrier of the signal s demodulated for each applied gain (Z1, Z2); calculating at least a part of the carrier leak based on the measured positions (PD1, PD2) and the applied gains (Z1, Z2), the calculated carrier leak part (offset_mod) corresponding to the leak due to the modulator.
