Multi-core optical transmission system based on high security cluster mapping based on trellis coding modulation

Abstract

The invention discloses a high-security clustering mapping multi-core optical transmission system based on trellis coding modulation, comprising: a network coding modulation module, which is used for serial-parallel conversion on an input original bit stream to obtain a parallel bit stream; a two-dimensional The constellation clustering mapping module is used to obtain a two-dimensional constellation map based on the two-dimensional constellation and parallel bit stream mapping. The three-dimensional constellation clustering mapping module is used to expand the parallel bit stream from the two-dimensional constellation diagram to the three-dimensional geometric constellation diagram based on the clustering mapping algorithm; the three-dimensional constellation encryption module is used to select the Chua's chaotic model and generate the disturbance vector; based on the disturbance vector, generate a chaotic quaternion matrix of three-dimensional space perturbation, and perturb the three-dimensional geometric constellation into a three-dimensional spherical constellation. The two-dimensional constellation and Viterbi decoding module is used to restore the cubic constellation diagram into a two-dimensional constellation diagram according to the clustering mapping algorithm to obtain the two-dimensional symbol information; perform Viterbi decoding on the two-dimensional symbol information to obtain the original bits flow.
