Aperiodic Hamming correlation (APHC) is more accurate to measure performances of the frequency hopping (FH) communication systems than periodic Hamming correlation. A class of no-hit-zone FH sequences (FHSs) with respect to APHC which has not yet been studied previously, is studied. A bound on no-hit-zone FHSs with respect to APHC is established. Further, a class of no-hit-zone FHSs with respect to APHC is constructed, which is optimal with respect to the new bound.
