Maximilian Matthe 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).

  • Orthogonal multicarrier transmission system using conjugate-root Offset-QAM
    Patent number: 9736001
    Abstract: In an orthogonal multicarrier radio transmission system complex-valued symbols are transmitted, wherein the real part and the imaginary part of each symbol are shifted against each other by one half symbol period and wherein a non-symmetric conjugate-root filter is applied to each symbol before transmission to mitigate inter-carrier interference and intersymbol interference. Corresponding reverse steps are performed at the receiver.
    Type: Grant
    Filed: December 7, 2015
    Date of Patent: August 15, 2017
    Assignee: Vodafone GmbH
    Inventors: Maximilian Matthe, Gerhard Fettweis, Ivan Gaspar
  • Walsh-hadamard transformed GFDM radio transmission
    Patent number: 9680540
    Abstract: A radio transmission system based on a frequency divisional multiplexing method is described, wherein a transmit symbol comprises a plurality of data symbols assigned to at least two subcarriers. The information of symbols of one time slot is spread across the data symbols of subcarrier of the time slot to produce a transmit symbol being more robust to frequency selective channels.

  • Generalized frequency division multiplexing radio transmission using frequency domain offset-QAM
    Patent number: 9628317
    Abstract: In a multicarrier radio transmission system complex-valued symbols are assigned to at least a first subcarrier and a second adjacent subcarrier, wherein the symbols assigned to the second subcarrier are offset in frequency by half a subcarrier against the symbols assigned to the first subcarrier.

  • ORTHOGONAL MULTICARRIER TRANSMISSION SYSTEM USING CONJUGATE-ROOT OFFSET-QAM
    Publication number: 20160164712
