| Abstract: |
| In order to design frequency encode and frequencyhopping(FH) sequence in
differential frequencyhopping(DFH) system, a differential frequency encode bas
ed on chaos mapping is provided, and Markov character of frequency state transf
er in frequency encode is analyzed. The statistical results show that the frequ
encyhopping sequences driven by chaos differential frequency encode have bette
r uniformity and randomness, which is effective to construct DFH transfer functi
on with higher linear complexity. |
