Chiara Martinelli-Cattaneo 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 and device for notching the transmission band of an analog signal, in particular for a detect and avoid (DAA) operation mode of an MB-OFDM system
    Patent number: 8396145
    Abstract: A transmission band of an analog signal including successive symbols to be transmitted is notched, where each symbol includes sub-carriers to be modulated. In particular, in each symbol the sub-carriers corresponding to a part of the transmission band to be notched are suppressed. In addition, in each symbol a chosen part of the remaining sub-carriers to be modulated is also suppressed.
    Type: Grant
    Filed: May 29, 2009
    Date of Patent: March 12, 2013
    Assignee: STMicroelectronics N.V.
    Inventors: Miguel Kirsch, Régis Cattenoz, Stéphane Tanrikulu, Chiara Martinelli-Cattaneo
  • Method and device for carrying out flexible demodulation in an OFDM-CDMA system
    Patent number: 7974357
    Abstract: This method for carrying out the flexible demodulation of data modulated following an amplitude modulation in quadrature is used in a communications system employing a code division multiple access technique (CDMA) and an optical frequency division multiplexing (OFDM) using non-binary spread codes. The invention includes steps for determining a simplified expression specific to the logarithm of the likelihood ratio.
