This paper presents a channel coding transmission mechanism in wireless and mobile networks by using the cross-packet transmission method of the sub-block structure to solve the problem of the poor quality of the network mobile multimedia. The present channel coding technology has the protective effect aiming to the data transmission in the mobile network. However, the present channel coding technology faces many kinds of network transmission phenomenon under the limited bandwidth constraint, including those comprehensive problems caused by the network congestion and the signal error. The poor efficiency of the data recovery and the bandwidth utilization is still one of the channel coding’s main defects. Compared with the present technologies, the experimental results demonstrate that the proposed method can achieve better bandwidth utilization by means of using sub-block coding structure to combat with small amount of transmission errors. Furthermore, the data recovery performance can be improved based on the two following facts about the cross -packet transmission: 1) the channel coding capacity is beyond a single packet and 2) both packet loss and signal error can be recovered simultaneously.
