Hybrid Character Sums From Vectorial Dual-Bent Functions and Asymptotically Optimal Complex Codebooks With Small Alphabet Sizes

Ziling Heng, Peng Wang, Chengju Li

Hybrid character sums are an important class of exponential sums which have nice applications in coding theory and sequence design. Let $\gf_{p^m}$ be the finite field with $p^{m}$ e…

New constructions of asymptotically optimal periodic and aperiodic quasi-complementary sequence sets

Peng Wang, Ziling Heng, Chengju Li

Quasi-complementary sequence sets (QCSSs) play an important role in multi-carrier code division multiple access (MC-CDMA) systems as they can support more users than perfect comple…

Weight distributions of cyclic codes with respect to pairwise coprime order elements

Chengju Li, Qin Yue, Fengwei Li

Let $F_{r}$ be an extension of a finite field $F_{q}$ with $r = q^{m}$ . Let each $g_{i}$ be of order $n_{i}$ in $F_{r}^{*}$ and $g cd (n_{i}, n_{j}) = 1$ for $1 \leq i \neq = j \leq u$ . We de…

Weight distribution of two classes of cyclic codes with respect to two distinct order elements

Chengju Li, Qin Yue

Cyclic codes are an interesting type of linear codes and have wide applications in communication and storage systems due to their efficient encoding and decoding algorithms. Cyclic…
