  • Patent number: 9432770
    Abstract: A method for localizing one or more sound sources of interest placed within a sound environment comprising ambient noise by estimating the directions of arrival (?,?) of said one or more sound source of interest comprising the steps of: calculating the environment steered response power (SRP (t, f, ?, ?)) corresponding to the steered response power of said one or more source of interest for one or more orientations using said environment audio signals; obtaining, using said array of at least two microphones, noise audio signals corresponding to the audio signals emanating from said sound environment under particular reference conditions; calculating a noise steered response power (SRPn (t, f, ?, ?)) corresponding to the steered response power of the ambient noise for said one or more orientations using said noise audio signals; and estimating the direction of arrival of said sound source of interest.

  • Patent number: 7424070
    Abstract: In order to evaluate the noise related to data issuing from a turbo-encoder, estimates of the noise related to its systematic output, to the data issuing from its first elementary encoder, and to the data issuing from its second elementary encoder are determined. At least two of the estimates of the noise related to the systematic output, to the data issuing from the first encoder, and to the data issuing from the second encoder, are added. The results of these additions are divided by the number of augends added, and then inverted, so as to obtain a noise factor, and the noise factor is multiplied with the data issuing from at least one of the first encoder, second encoder, and systematic output.

  • Patent number: 7260653
    Abstract: The present invention relates to a method of synchronization between communication networks exchanging information by frame of informations, each communication network having clock and the number of clock pulses is monitored by a counter the synchronization is made by reading information representing the counted clock pulses of the clock of the first network at the appearance of a reference event, inserting at least said information or calculated information on the basis of said information into the frame of information as the synchronization information, transferring said frame of information from the first to the second network, reading information representing the number of counted clock pulse of the clock of the second network at the appearance of reference event, reading synchronization information inserted in received frame of information from the first network, calculating a difference between information and synchronizing the second network.

  • Patent number: 7058729
    Abstract: The present invention relates to a method of synchronisation between communication networks exchanging information by frame of informations, each communication network having clock and the number of clock pulses is monitored by a counter. The synchronisation is made by reading information representing the counted clock pulses of the clock of the first network at the appearance of a reference event, inserting at least said information or calculated information on the basis of said information into the frame of information as the synchronisation information, transferring said frame of information from the first to the second network, reading information representing the number of counted clock pulse of the clock of the second network at the appearance of reference event, reading synchronisation information inserted in received frame of information from the first network, calculating a difference between information and synchronising the second network.

  • Patent number: 7039120
    Abstract: The method of transmitting data in the form of symbols sent over an electromagnetic channel is characterized in that a measurement of significance is attributed to each group of data to be transmitted, in that the transmission reliability of the carriers is estimated dynamically, and in that the most significant data are sent over the most reliable carriers at each instant, the other data being sent over the carriers of decreasing reliability, in decreasing order of significance of the data.
