摘要： A method of determining topographical interference with a guided missile is proposed. The method may include obtaining a pre-calculated expected trajectory of a guided missile. The method may also include extracting topographic elevations with respect to a topography corresponding to the pre-calculated expected trajectory from stored topographical information. The method may further include determining presence or absence of topographical interference with the guided missile based on bottom trajectory elevation values in the pre-calculated expected trajectory and topographic elevation values corresponding to the bottom trajectory elevation values. The pre-calculated expected trajectory may include top, bottom, left, and right trajectories with respect to a launch direction of the guided missile, calculated based on an error factor for the guided missile, and the error factor includes manufacturing error values with respect to at least one of a weight, center of gravity, a thrust, or a moment of inertia of the guided missile.

摘要： A transmission apparatus of a single carrier-based wireless communication system is proposed. The transmission apparatus may include a transceiver, a memory configured to store one or more instructions; and a processor configured to execute the one or more instructions stored in the memory. The processor may generate data symbols by modulating traffic data, generate a cyclic prefix (CP) on the basis of the data symbols, and generate a pilot symbol for the data symbol. The transceiver may transmit a single carrier frequency domain equalizer (SC-FDE) frame including the data symbol, the CP, and the pilot symbol. The data symbols may include first data symbols and second data symbols. The pilot symbol may be transmitted after transmission of the first data symbols and before transmission of the second data symbols.

摘要： Proposed is a cyberattack scoring method performed by a cyberattack scoring device including a memory storing one or more instructions and a processor executing the one or more instructions stored in the memory. The method may include determining a tactic for each of unit attacks included in a cyberattack based on an Adversarial Tactics, Techniques, and Common Knowledge (ATT&CK) framework. The method may also include determining a score for each of the unit attacks by calculating a weighted sum on attributes depending on the determined tactic according to priorities. The method may further include determining the score of the cyberattack by summing the determined scores of the unit attacks.
