Uniformity, good Hamming‐correlation and long period are critical requirements for frequency‐hopping (FH) sequence set. A new class of no‐hit zone FH (NHZ‐FH) sequence set is designed based on chaotic nonlinear map to meet above three demands. Some properties of the proposed sequence set and its performance for frequency‐hopping‐multiple‐access (FHMA) system are investigated. The results show that the proposed NHZ‐FH sequence set can offer more robustness to eavesdropper and lower BER for quasi‐synchronous FHMA system in comparison with other traditional FH sequence sets.
