Improved Singleton bound on insertion-deletion codes and optimal constructions
Bocong Chen, Guanghui Zhang
Insertion-deletion codes (insdel codes for short) play an important role in synchronization error correction. The higher the minimum insdel distance, the more insdel errors the cod…
Constructions of cyclic constant dimension codes
Bocong Chen, Hongwei Liu
Subspace codes and particularly constant dimension codes have attracted much attention in recent years due to their applications in random network coding. As a particular subclass…
New constructions of MDS codes with complementary duals
Bocong Chen, Hongwei Liu
Linear complementary-dual (LCD for short) codes are linear codes that intersect with their duals trivially. LCD codes have been used in certain communication systems. It is recentl…
Constacyclic symbol-pair codes: lower bounds and optimal constructions
Bocong Chen, Liren Lin, Hongwei Liu
Symbol-pair codes introduced by Cassuto and Blaum (2010) are designed to protect against pair errors in symbol-pair read channels. The higher the minimum pair distance, the more pa…
Three new classes of optimal frequency-hopping sequence sets
Bocong Chen, Liren Lin, San Ling +1
The study of frequency-hopping sequences (FHSs) has been focused on the establishment of theoretical bounds for the parameters of FHSs as well as on the construction of optimal FHS…
Construction of Self-dual Codes over
Guanghui Zhang, Bocong Chen
In this paper, we determine all self-dual codes over () in terms of self-dual codes over the finite field and give an explicit construction for self-dual co…
