Method for realizing frequency-hopping communication in strong electromagnetic interference environment

The invention relates to a frequency-hopping communication method, in particular to a method for realizing a frequency-hopping communication in a strong electromagnetic interference environment. The method comprises the following steps: (1) building of a frequency-hopping system mathematical model: performing baseband modulation on an input information code sequence, synchronizing a receiving party and a transmitting party under the control of a frequency-hopping sequence controller, and finishing reception and transmission of a frequency-hopping signal; (2) building of frequency-hopping synchronization: acquiring a correct intermediate-frequency frequency with the same frequency at the same moment through a frequency-hopping receiver and a frequency-hopping transmitter; (3) determination of a frequency-hopping pattern: selecting a coefficient in a Galois field through a frequency-hopping pattern design based on an RS code, and performing transformation; and (4) networking of the frequency-hopping communication: extending the coverage of a radio station to perform networking. The method has the advantages and effects that the bit error rate of a system can be reduced to improve the overall performance of the system. The anti-interference capability in the communication is enhanced. In particular, the communication confidentiality and transmission reliability are enhanced in a complex battlefield communication environment. Moreover, a plurality of frequency-hopping systems can work at the same time within a certain broadband through different frequency-hopping patterns in the frequency-hopping communication, so that the system spectrum utilization ratio is increased greatly.
