摘要： 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.

摘要： 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.
