Asymptotic Properties of Quasi-Group Codes
Yun Fan, Liren Lin
This is a manuscript of a chapter prepared for a book. The good codes possess large information length and large minimum distance. A class of codes is said to be asymptotically goo…
Avoiding unwanted results in locally linear embedding: A new understanding of regularization
Liren Lin
We demonstrate that locally linear embedding (LLE) inherently admits some unwanted results when no regularization is used, even for cases in which regularization is not supposed to…
Self-dual -quasi-abelian Codes
Liren Lin, Yun Fan
A kind of self-dual quasi-abelian codes of index over any finite field is introduced. By counting the number of such codes and the number of the codes of this kind whose re…
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…
Mixed dimensional infinite soliton trains for nonlinear Schrödinger equations
Liren Lin, Tai-Peng Tsai
In this note we construct mixed dimensional infinite soliton trains, which are solutions of nonlinear Schrödinger equations whose asymptotic profiles at time infinity consist of in…
