“…However, if the adjacent time slots of the FHS are greater than a given value. Such an FHS is called wide-gap FHS (WGFHS) [19], [20]. In this way, even if it is subject to strong single frequency interference, it will only lose information in one time slot, but not in several consecutive time slots.…”

The frequency hopping sequence plays a crucial role in determining the system's anti-jamming performance, in frequency hopping communication systems. If the adjacent frequency points of FHS can ensure wide-gap, it will better improve the anti-interference capability of the FH communication system. Moreover, if the period of the sequence is expanded, and each frequency point does not repeat in the same sequence, the system's ability to resist electromagnetic interference will be enhanced. And a one-coincidence frequency-hopping sequence set consists of FHSs with maximum Hamming autocorrelation 0 and cross-correlation 1. In this paper, we present two constructions of wide-gap frequency-hopping sequence sets. One construction is a new class of wide-gap one-coincidence FHS set, and the other is a WGFHS set with long period. These two WGFHS sets are optimal with respect to WG-Peng-Fan bound. And each sequence of these WGFHS sets is optimal with respect to WG-Lempel-Greenberger bound.

“…Such as the urgent need to improve spectrum utilization of the communication system, the urgent need to enhance the network capacity of the system, and the urgent need to improve the system of comprehensive antiinterference ability. In order to alleviate the dilemma caused by the above problems to people's increasing demand for wireless access, the wide-gap frequency-hopping sequence (WGFHS) was proposed [29], [34]. The basic idea is that if the spectrum span of the adjacent frequency of a user is large enough, even if a certain frequency hopping signal falls into the interference frequency band, the adjacent frequency hopping signal will not be interfered, and the interfered information can be recovered by coding.…”

In frequency-hopping systems, there should be a wide frequency-hopping gap between two adjacent frequencies in case the received signals are prone to be interfered by staying at one frequency point for a long time. In this paper, a bound on the maximum partial Hamming autocorrelation of widegap frequency-hopping sequences (WGFHSs), two bounds on the maximum partial Hamming correlation of WGFHS sets, two bounds on the maximum Hamming correlation of WGFHS sets with low hit zone and two bounds on the maximum partial Hamming correlation of WGFHS sets with low hit zone are derived. Moreover, the proposed bounds are tighter than the Eun-Jin-Hong-Song bound, Zhou-Tang-Niu-Udaya bounds, Peng-Fan-Lee bounds and Niu-Peng-Liu bounds in the sense that they can be achieved by the parameters of some WGFHSs. To the best of our knowledge, these bounds are obtained for the first time in the literature. INDEX TERMS Wide-gap frequency-hopping sequence, partial Hamming correlation, low hit zone.

“…Under the guidance of theoretical bound, many FHS sets with excellent properties are created by using various algebraic or combinatorial tools (e.g., see [5][6][7]). Among them, the wide-gap frequency-hopping sequences (WGFHSs) have distinctive characteristics, that is, their neighbouring FH gaps are wide enough [6,7]. The neighbouring hop signal will not be interfered, even if a certain hop signal is in the interference band, and the interfered information could be recovered through coding.…”

With the rapid development of radar, the phenomenon of Doppler frequency shift is not rare. Frequency shift needs to be considered in order to accurately calculate the mutual interference between signals. Meanwhile, to reduce interference to the received signal, each user's frequency hopping sequence shall have wide frequency hopping gap. The authors introduce the time‐frequency two‐dimensional Hamming correlation function and extend the bounds for wide‐gap frequency‐hopping sequences. The Li–Fan–Yang–Wang bounds are the special cases of our bounds for frequency shift is zero.
