Abstract
Kitayama proposed a novel OCDMA (called spatial CDMA) for parallel transmission of 2-D images through multicore fiber. Optical orthogonal signature pattern codes (OOSPCs) play an important role in this CDMA network. Multiple-weight (MW) optical orthogonal signature pattern code (OOSPC) was introduced by Kwong and Yang for 2-D image transmission in multicore-fiber optical code-division multiple-access (OCDMA) networks with multiple quality of services (QoS) requirements. Some results had been done on optimal balanced $ (m, n, \{3, 4\}, 1) $-OOSPCs. In this paper, it is proved that there exist optimal balanced $ (2u, 16v, \{4, 5\}, 1) $-OOSPCs for odd integers $ u\geq 1 $, $ v\geq 1 $.
