The Cross-Correlation Distribution of the Niho-Type Decimation $d = 4 (2^{m} - 1) + 1$

Maosheng Xiong, Haode Yan

The cross-correlation problem is a classical problem in sequence design. In this paper, we determine the cross-correlation distribution of the Niho-type decimation $d = 4 (2^{m} - 1) + 1$ o…

Counterexamples to Charpin's Conjecture on BCH codes

Run Zheng, Yaoran Yang, Yutong Zhang +2

We construct an infinite family of $q$ -ary primitive narrow-sense BCH codes whose minimum distance strictly exceeds the Bose distance; in fact, the gap between the two can be arbit…
