Information transmission based on a Fourier transform and ascending coding temporal ghost imaging algorithm

Abstract

Abstract In this paper, based on the specific analysis of a temporal ghost imaging (TGI) algorithm, image coding transmission is realized by combining the compression characteristics of a Fourier transform, the convenient control and management function of ascending coding (AC) and the precise transmission function of TGI. AC, as a kind of sorting coding, has the characteristics of fast speed, high precision and wide application range. This paper analyzes noise attack, information, bit error rate (BER) and similarity, etc. Verified by simulation experiment, this algorithm can improve the compressibility of the encoded image, improve the difficulty of decoding by an attacker, reduce the BER in the process of image coding transmission, enhance the ability of anti-interference, realize accurate image coding transmission and solve the problems of low accuracy and low security of image transmission reconstruction at present.
