Maximum w-cyclic holely group divisible packings with block size three and applications to optical orthogonal codes
In this paper we investigate combinatorial constructions for w-cyclic holely group divisible packings with block size three (briefly by 3-HGDPs). For any positive integers u,v,w with u≡0,1 ( 3), the exact number of base blocks of a maximum w-cyclic 3-HGDP of type (u,w^v) is determined. This result is used to determine the exact number of codewords in a maximum three-dimensional (u× v× w,3,1) optical orthogonal code with at most one optical pulse per spatial plane and per wavelength plane.
