  • Sorting-based detection of a skywave symbol
    Patent number: 12375160
    Abstract: A method for detecting a skywave symbol, the method may include (i) receiving, by a skywave receiver, signals of different subcarriers that are within a skywave frequency range that comprises legal subcarriers and illegal subcarriers; (ii) performing sorting iterations to provide a sorted list of signals intensities; and (iii) providing a detection result indicative of a reception of the skywave symbol based on at least some members of the sorted list.

  • Priority based transmission
    Patent number: 11265891
    Abstract: There may be provided a method for priory based transmission of skywave symbols, the method may include starting to transmit a first skywave symbol; determining to stop a transmission of the first skywave symbol and to transmit a second skywave symbol that has a higher priority than the first skywave symbol; stopping the transmission of first skywave symbol before a completion of the transmission of the first skywave symbol thereby transmitting a partial first skywave symbol; and transmitting the second skywave symbol.

  • Reconstruction of a skywave symbol
    Patent number: 10785077
    Abstract: A method for symbol reconstruction, the method comprises: receiving, by a skywave propagation receiver, a partial skywave symbol that comprises a first number (N1) of of legal subcarriers out of a set of a second number (N2) of legal subcarriers that represent a given skywave symbol; wherein the given skywave symbol belongs to a group of skywave symbols; wherein each pair of skywave symbols of the group share up to a third number (N3) of legal subcarriers; and selecting the given skywave symbol from the group when N1 exceeds N3.
