  • Publication number: 20240028903
    Abstract: A control device is used in a vehicle including a perception system which uses sensors. The perception system includes a device for estimating a variable including a characteristic relating to objects detected in the surrounding area of the vehicle, the estimation device including an online learning module which uses a neural network to estimate the variable. The learning module includes: a forward-propagation module to propagate data from sensors, which data are applied as the input to the neural network, so as to provide a predicted output including an estimate of the variable; a fusion system to determine a fusion output by implementing a sensor fusion algorithm using the predicted values; a back-propagation module to update weights associated with the online neural network by determining a loss function representing the error between an improved predicted value of the fusion output and the predicted output by performing gradient descent back propagation.

  • Patent number: 8953702
    Abstract: A process selects a Precoding Matrix Index (PMI) in a Multiple In Multiple Out (MIMO) receiver used in a wireless communications system including a base station communicating with User Equipments (UE) through a downlink and uplink channel. The base station applies a precoding on the transmit symbol vector based on a matrix selected from a set of predefined matrices and identified by a PMI index computed by the UE and forwarded to the base station via the uplink. The process includes estimating the MIMO channel matrix H of a given set of resources blocks comprising received symbol vectors, estimating the variance ?2 of the additive noise (AWGN), and computing for each particular matrix comprised within the set of predefined matrices a cost function representative of the orthogonality of the matrix MIMO channel matrix H.

  • Patent number: 8861651
    Abstract: A process for performing a QR Decomposition of a channel matrix of a wireless communication channel system, said process involving the steps of: performing a full QR Decomposition of one channel matrix for the purpose of deriving a first QR representation of the channel; performing a second iterative QR Decomposition of an adjacent channel matrix, said second iterative QR Decomposition using the results of said first QR representation as well as the difference of the two adjacent channel matrices ?H. More particularly, the process is characterized in that the iterative QR Decomposition is performed in response to the detection of a high level of workload of the processor.

  • Patent number: 8855347
    Abstract: A hearing device comprises an ear-piece which is designed to be worn at least partially in an ear canal of a user of the hearing device. The ear-piece comprises a vent passage connecting the ear canal with the atmosphere. The vent passage has an inner opening towards the ear-canal and an outer opening towards the atmosphere. The ear-piece further comprises a vent extension. The vent extension is a protrusion extending the vent passage beyond the body of the ear-piece. The vent extension is adapted for abutting on a surface of the body of the user and is thereby inconspicuous and/or contributes thereby to retention. A method for manufacturing such a hearing device is also disclosed.

  • Patent number: 8705665
    Abstract: A process for computing Log-Likelihood-ratios (LLRs) in a detector of a wireless communication receiver is disclosed, with the, LLRs being used by a channel decoder. A signal is received from a telecom front end, the signal corresponding to data belonging to a finite set of constellation symbols, each constellation symbol being arranged in a lattice constellation impaired by additive noise and a multiplicative channel. A limited set of distances representative of Euclidian distances between the received signal and a finite set of predetermined constellation symbols are computed, possibly multiplied by the channel. A set of soft decision LLRs are derived from the computed set of distances under the constraint of a limited length of the list of distances. The derived LLRs are completed by clipping values read from a look-up table which is simultaneously addressed by the values of the SNR and a bit index.
