Abstract

The increasingly severe situation of information security puts forward higher requirements for wireless communication transmission. Minimum shift keying (MSK) offers outstanding advantages, including the constant signal envelope, the narrow main lobe of the power spectrum, and strong channel adaptability. It can be used to increase the modulation map diversity and achieve the purpose of waveform encryption of the transmit signal. As a result, this paper proposes the MSK modulator structure hopping (MSKMSH) method for physical layer secure transmission. Firstly, a set of MSK modulator structures with a space size of 16 is constructed according to signal waveform characteristics. Secondly, the pattern set generated by the structure hopping law is analyzed to ensure traceless conversion between different MSK modulators. Finally, a data-assisted synchronization scheme utilizing unique characters is designed to synchronize the legitimate destination and the source with structure hopping. Through simulation experiments and theoretical analysis, it is demonstrated that the MSKMSH method can realize reliable and secure transmission of radio signals.
