Patents by Inventor Henning VETTER

Henning VETTER 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).

  • Multi-antenna wireless communications method and apparatus with vector perturbation with a reduced lattice
    Patent number: 8718180
    Abstract: Precoding information prior to MIMO transmission is described, comprising determining a suitable preceding perturbation. The perturbation is determined by assembling a list of candidate perturbations in reduced lattice space, transforming these back into information lattice space and determining which candidate precoder perturbation is most suitable given a performance criterion.
    Type: Grant

    Date of Patent: May 6, 2014
    Assignee: Kabushiki Kaisha Toshiba
    Inventors: Henning Vetter, Vishakan Ponnampalam
  • Wireless communication method and apparatus
    Patent number: 8619892
    Abstract: The present invention provides a method of processing information prior to an emission from a multi-antenna device in a multi-user network having at least one user, said emission comprising transmission of a plurality of subcarriers comprising pilot symbols and data symbols, and said information being a data vector, the method comprising arranging said pilot symbols and said data symbols such that at least one of said plurality of subcarriers comprises at least one of said pilot symbols and at least one of said data symbols, wherein said data vector corresponds to said at least one of said plurality of subcarriers such that said data vector comprises data elements corresponding to said at least one of said pilot symbols and said at least one of said data symbols, precoding said data vector prior to transmission, and the precoding comprising applying a perturbation to said data vector in order to generate a perturbed data vector in which data elements corresponding to the pilot symbol remain unperturbed, and s
