| Abstract: | Error control technology,which is the main content of wireless transmission technology of compressed digital image,is discussed in this paper. A constant-length data frame encoding method based on HEC & the criterion for selecting its key parameter are proposed. The result of the experiment shows that the method reduces error rate of wireless transmission and maintains the efficiency as well. |
