Abstract
A method for detection of a skywave symbol, the method may include receiving, by a skywave propagation receiver, received signals that are within a skywave frequency range that comprises legal subcarriers and illegal subcarriers; and detecting a reception of the skywave symbol based on at least one energy parameter related to at least two out of (a) received signals at the illegal subcarriers, (b) received signals at the legal subcarriers, (c) received signals at any of the subcarriers.
Claims12
A method for detection of a skywave symbol, the method comprises:
- receiving, by a skywave propagation receiver, received signals that are within a skywave frequency range that comprises legal subcarriers and illegal subcarriers;
- and
- detecting a reception of the skywave symbol based on an energy parameter related to received signals at the illegal subcarriers that are received during a time window, and to received signals at the legal subcarriers that are received during the time window.
A non-transitory computer readable medium that stores instructions for:
- receiving, by a skywave propagation receiver, received signals that are within a skywave frequency range that comprises legal subcarriers and illegal subcarriers;
- and
- detecting a reception of the skywave symbol based on an energy parameter related to (a) received signals at the illegal subcarriers that are received during a time window, and (b) received signals at the legal subcarriers that are received during the time window.
A skywave propagation receiver that comprises a receiving unit that is configured to receive signals that are within a skywave frequency range that comprises legal subcarriers and illegal subcarriers;
- and a processor that is configured to detecting a reception of the skywave symbol based on an energy parameter related to (a) received signals at the illegal subcarriers that are received during a time window, and (b) received signals at the legal subcarriers that are received during the time window.
