摘要
论文将信道编码与多载波调制——滤波多音(FMT,filtered multitone)调制技术相结合,并应用到图像的传输中,通过采用调整Punctured卷积码不同的码率实现图像传输的不等错误保护(UnequalErrorProtection),增加了系统的可靠性,又提高系统传输效率,满足在具有不等错误保护要求的无线环境下对传输图像质量的要求。
Filtered muhitone modulation combines with channel coding,which are applied to image transmission over multipath channel.We have proposed a scheme of Unequal Error Protection（UEP） in image transmission by means of adjusting different rate of punctured convolutional codes.Simulation results show superiority of the UEP with improving system＇s reliability and efficiency .
