Wide Interval Frequency Hopping Sequence Constructed by Using Frequency Band Division Method

To strengthen the confidentiality of the dual-band method, a new method added randomness - frequency band division is proposed. At first, the given frequency band is evenly divided, and every frequency of different bands corresponds to each other. Then a frequency band table with randomness prior or average interval prior is generated to control hopping and changing among bands. Core idea of the dual-band method is inherited and the cycle length won´t be changed. Theoretical analysis and simulation with Mat lab show that sequences generated by the proposed method perform well. On the premise that Hamming correlation property doesn´t worsen, confidentiality and balance have been further improved and the method can be used as an effective method of wide interval processing.
