Anti-jamming method in satellite communication (SATCOM) system

An anti-jamming method in a satellite communication (SATCOM) system, comprising:

• performing a waveform modulation on a waveform of a source data to provide a modulated waveform;
• transmitting the modulated waveform to a transmitter and then to a receiver;
• demodulating the modulated waveform transmitted from the receiver to provide a demodulated waveform;
• in response to an interference of a jammer, performing a game reasoning process on the demodulated waveform to provide an anti-jamming adaptive waveform, wherein:
• a game player 1 and a game player 2 are included in the game reasoning process, the game player 1 is the jammer, and the game player 2 is the SATCOM system, according to an impudent random process each player in the game reasoning process discovers exploits of the other player;
• once the jammer detects an exploit of the SATCOM system, the jammer chooses to respond according to a game-optimal solution by which the SATCOM system's possible actions and associated consequences are compared and sorted;
• and
• the exploit of the SATCOM system at least includes:
• a currently-used band frequency and a current communication link between a current satellite and a terminal for the data transmission;
• and
• performing the waveform modulation after the game reasoning process on the anti-jamming adaptive waveform to guide a frequency hopping process for data transmission, such that the source data is transmitted with a minimal probability of being interfered.
