N2 - The M-sequence has property of good self-correlative, it has pseudo random property and it is easy to be generated and copied. It mainly be applied to spread spectrum and encryption. Traditional information synchronize way based m-sequence realize information synchronize of transmitter and receiver by periodicity of spread spectrum code. When transmitter sending information in every rate, there will be synchronization sequence made by M-sequence added in the part of information after these information are split. Receiver get the useful information when it detect the synchronization sequence made by m-sequence. There are some spurious triggering appear in information synchronization of various rate or information synchronization of front and back. A novel system of airborne data link based on the spread spectrum and information synchronize is designed in this paper. Analyzed the basic principle, structure and property of M-sequence, realizes m-sequence with the methods of MATLAB programming. Design and application of m-sequence is applied in this airborne data link system. The characteristic of the new method of spread spectrum is generating and filtering m-sequence by the generator of M-sequence, then split it to 6 to 8 section of synchronization sequence used in series. The spurious triggering of information synchronization of front and back will be reduced substantially due to the different synchronization sequence. Besides, the spurious triggering of various rate will be reduced substantially too, because of the use of sectionalized information synchronization in series. This method of spread spectrum is also promoting the system capacity, the capacity of resisting disturbance and the capacity of confidentiality.
