  • Patent number: 8929495
    Abstract: A method for equalizing the received signal in communications based on filterbank multicarrier modulations and, more particularly, to such a method and system especially advantageous in situations where the channel frequency selectivity is exceptionally high. The method significantly improves the performance of traditional filterbank equalization algorithms based on finite impulse response filters at the output of the receive filterbank. Furthermore, the system consists of multiple parallel stages, the number of which can be tuned to achieve a good compromise between performance and computational complexity. Thanks to this modular structure, and to the fact that most of the architecture can be efficiently implemented using fast Fourier transforms, the system presents a very low computational complexity compared to more traditional equalizers for filterbank multicarrier modulations.

  • Publication number: 20130006328
    Abstract: A cochlear prosthesis comprising an electrical signal analyser configured to process a first frequency sub-range of a detected sound signal for electric stimulation of the cochlea, and a delay circuit configured to impose a delay on at least one of an electrical signal delivery path and an acoustic signal delivery path, to provide for delivery of the electrical stimulation to the cochlea at a desired time relative to a time of arrival of acoustic stimuli at the cochlea, wherein the acoustic stimuli arriving at the cochlea and the electrical stimulation delivered to the cochlea at the desired time substantially simultaneously stimulate the cochlea.

  • Patent number: 8285382
    Abstract: An embodiment of the present invention takes masking effects into consideration when determining stimulation signals for neural stimulation. These masking effects may be modeled using user-specific models determined by taking measurements for an implant system of an implant recipient. Or, the model may correspond to a group of individuals sharing a common characteristic or the population as a whole. These models may be, for example, psycho-physical models.

  • Publication number: 20060287690
    Abstract: A bimodal hearing prosthesis configured to deliver electrical and acoustic stimulation to a recipient such that a frequency range of a received sound that is represented by the electrical stimulation is perceived simultaneously with the frequency range of the received sound that is represented by the acoustic stimulation.
