The design of hopping sequence in VHF Hopping Radio and random nature analysis

摘要

Hopping sequence used in VHF Hopping Radio ought to have a longer period, therefore the partial and dynamic properties of balance and Hamming correlation are more essential in practical hopping sequences application. Based on m sequence of GF(p) structure we had designed hopping sequence. The paper uses χ² statistic test for partial of hopping sequence homogeneity, frequency interval stay, run-length, hamming correlation and exclusive of partial hopping sequence, and briefly analyzes the test results. The results show that partial hopping sequence with the sequence length increases, its random nature is approaching the performance of the entire periodic sequence.
