【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。更多还原

【Abstract】 Filtered multitone 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 .更多还原
