Generalized perfect difference families and their application to variable-weight geometric orthogonal codes
Xiaowei Su, Lidong Wang, Zihong Tian
Motivated by the application in geometric orthogonal codes (GOCs), Wang et al. introduced the concept of generalized perfect difference families (PDFs), and established the equival…

Maximum -cyclic holely group divisible packings with block size three and applications to optical orthogonal codes
Zenghui Fang, Junling Zhou, Lidong Wang
In this paper we investigate combinatorial constructions for -cyclic holely group divisible packings with block size three (briefly by -HGDPs). For any positive integers $u,v…

Optimal optical orthogonal signature pattern codes with weight three and cross-correlation constraint one
Rong Pan, Tao Feng, Lidong Wang +1
Optical orthogonal signature pattern codes (OOSPCs) have attracted wide attention as signature patterns of spatial optical code division multiple access networks. In this paper, an…
