摘　　要：随着计算机及通信等技术日新月异的发展,无线图像传输技术得到了广泛的重视。针对视频、图像传输效率低及通信系统性能没有达到最优等问题,在列出了基本概念基础上,本文提出了一种基于最大后验概率的联合信源信道编码算法,经过仿真验证,此方法图像质量比传统方法有所提高。With the development of ever-changing computer and communications technology,wireless video transmission technology has been widely appreciated.For the low transmission efficiency of video,image and system performance not optimal and so on,this paper presents a maximum a posteriori probability based on the joint source channel coding,through simulation results in the list of the basic concepts.Through simulation results,this method is more improved than the traditional method of image quality.
