Image Transmission in Multicore-Fiber Code-Division Multiple-Access Networks

Two-dimensional (2-D) signature patterns, so-called optical orthogonal signature pattern codes (OOSPC's), were recently proposed to encode binary digitized image pixels in optical code-division multiple-access (CDMA) networks with "multicore" fiber. The new technology enables parallel transmission and simultaneous access of 2-D images in multiple-access environment. However, previous work on OOSPC's assumed that the weight of every signature pattern in a code set was the same. In this paper, we construct and analyze a new family of OOSPC's without this assumption. Since the performance of a signature pattern varies with its code weight, our approach is useful for optical CDMA networks with a multiple performance requirement.
