Paper Abstract

A cyclically permutable code is a binary code whose codewords is cyclically distinct and has a full cyclic order. Important classes of these codes are the constant weight cyclically permutable codes. These codes have wide applications in optical code division multiple access communication systems. In this paper, we propose a tunable cyclic shifter based on the super-imposed holographic grating using photopolymer as the holographic medium, which can be used with a cyclically permutable code by applying appropriate strain to the photopolymer.
