Study of Channel Coding in Digital Static Picture Transmission

Abstract

This paper introduces a new technology that combines the modulation method with high frequency band utilization and high-efficiency error correction coding, and for the given modulation method in the specific digital static image transmission system, the convolution of R=1/2 According to the coding-mapping rule, the (7,5) code and the mapping rule-Gray mapping are discussed and practiced. Finally, the experimental results of wireless channel transmission are given.
