The work aims to reduce the information amount of image transmission when improving the resolution of the transmitted image, so as to improve the reliability and security of the channel, since channel noise interference, spectrum resource shortage and high error rate in the process of image transmission limit the quality and efficiency of image transmission and reduce the reliability of the channel. On the premise of making the most effective use of the transmission capacity of the Huffman coding channel, the error rate in information transmission was reduced as much as possible to integrate the channel coding redundant information and ghost imaging transmission channel information. The reliability of transmission signal was improved, data transmission quality was guaranteed, and stable and fast communication was realized. This work studies the image transmission mechanism based on channel coding ghost imaging, and makes full use of the lossless data compression characteristics of Huffman coding to improve the resolution of the transmitted image while reducing the information content of the transmitted image, so as to improve the reliability and security of the channel.
