Sequências de salto de frequência de zona de baixo acerto (LHZ-FHSs) são sequências de salto de frequência com baixa correlação de Hamming em uma zona de baixo acerto (LHZ), que têm aplicações importantes em sistemas de comunicação quase síncronos. No entanto, a quase-sincronização estrita pode ser difícil de manter em todos os momentos em redes FHMA práticas; também é necessário minimizar a correlação de Hamming para mudanças de tempo fora do LHZ. O principal objetivo desta carta é propor um limite inferior para a magnitude máxima de correlação fora da zona de baixo acerto para conjuntos LHZ-FHS. Acontece que o limite proposto é estreito ou quase apertado no sentido de que pode ser alcançado por alguns conjuntos LHZ-FHS.

Abstract: Low-hit-zone frequency-hopping sequences (LHZ-FHSs) are frequency-hopping sequences with low Hamming correlation in a low-hit-zone (LHZ), which have important applications in quasi-synchronous communication systems. However, the strict quasi-synchronization may be hard to maintain at all times in practical FHMA networks, it is also necessary to minimize the Hamming correlation for time-shifts outside of the LHZ. The main objective of this letter is to propose a lower bound on the maximum correlation magnitude outside the low-hit-zone for LHZ-FHS sets. It turns out that the proposed bound is tight or almost tight in the sense that it can be achieved by some LHZ-FHS sets.
