Abstract: Embedding multiple watermarks into a digital object enables multiple purposes to be realized. In this paper, we present a multi-party watermark embedding framework based on frequency-hopping sequences (FHSs). In the proposed work, a certain number… read more here.

DOI: 10.1109/tcomm.2022.3194983
Abstract: In this paper, two new families of asynchronous channel-hopping (CH) sequences—Symmetric Maximum-Length CH (SML-CH) Sequences and Relaxed Difference Set (RDS) of Maximum-Length CH (RDSML-CH) Sequences—are constructed. For the first time, the maximum-length sequences (also called… read more here.

DOI: 10.1109/tit.2021.3123395
Abstract: In frequency hopping (FH) communication systems, frequency hopping sequences (FHSs) are crucial in determining the system’s anti-jamming performance. If FHSs can ensure a wide-gap between two adjacent frequency points to avoid the frequency points with… read more here.
