摘　　要：针对现代战场对高速无线图像数据传输的需求,介绍了一种基于高效正交幅度调制的无线图传系统,并对其中重要的QAM元数值选择方法、编码映射设计方法、定时误差估计方法进行了分析计算。最后采用软件无线电的架构设计制作了基带处理平台,并通过仿真和实验进行了验证。To meet the demand of high data rate image transmission syetem in warfare condition,this paper introduces a system based on high efficiency quadrature amplitude modulation（QAM）, then analyzes three important theories, the selection of parameter M, the design method of Code Mapping, and the timing error estimation. In the end, based on the theory of software designed radio, the baseband hardware platform is designed. Moreover this design is verified through simulation and test.
