Constructions of involutions over finite fields

Dabin Zheng, Mu Yuan, Nian Li +2

An involution over finite fields is a permutation polynomial whose inverse is itself. Owing to this property, involutions over finite fields have been widely used in applications s…

Large Sets of Orthogonal Sequences Suitable for Applications in CDMA Systems

WeiGuo Zhang, ChunLei Xie, Enes Pasalic

In this paper, we employ the so-called semi-bent functions to achieve significant improvements over currently known methods regarding the number of orthogonal sequences per cell th…

A construction of $q$ -ary linear codes with two weights

Ziling Heng, Qin Yue

Linear codes with a few weights are very important in coding theory and have attracted a lot of attention. In this paper, we present a construction of $q$ -ary linear codes from tra…

On the Non-existence of certain classes of generalized bent functions

Chang Lv, Jianing Li

We obtain new non-existence results of generalized bent functions from \ZZ^n_q to \ZZ_q (called type [n,q]). The first case is a class of types where q=2p_1^{r_1}p_2^{r_2}. The sec…

A Sharp Condition for Exact Support Recovery of with Orthogonal Matching Pursuit

Jinming Wen, Zhengchun Zhou, Jian Wang +2

Support recovery of sparse signals from noisy measurements with orthogonal matching pursuit (OMP) has been extensively studied. In this paper, we show that for any $K$ -sparse signa…

Further results on differentially 4-uniform permutations over $\F_{2^{2m}}$

Zhengbang Zha, Lei Hu, Siwei Sun +1

In this paper, we present several new constructions of differentially 4-uniform permutations over $\F_{2^{2m}}$ by modifying the values of the inverse function on some subsets of $…

On the distinctness of binary sequences derived from $2$ -adic expansion of m-sequences over finite prime fields

Yupeng Jiang, DongDai Lin

Let $p$ be an odd prime with $2$ -adic expansion $\sum_{i = 0}^{k} p_{i} \cdot 2^{i}$ . For a sequence $a = (a (t))_{t \geq 0}$ over $F_{p}$ , each $a (t)$ belongs to $\{0,1,\ldot…

Distribution properties of compressing sequences derived from primitive sequences modulo odd prime powers

Yupeng Jiang, Dongdai Lin

Let $a$ and $b$ be primitive sequences over $Z / (p^{e})$ with odd prime $p$ and $e \geq 2$ . For certain compressing maps, we consider the distribution p…
