应用以Mobius变换为基础的Chen-Mobius通信系统的调制解调思想作为图像转换处理的方法，把数字信号作为调制载波信号，在接收端用与数字信号相正交的Chen-Mobius逆变换函数族进行向步相干解调．以数字图像信号波形作为原始输入信号分别通过传统通信系统和Chen—Mobius通信系统进行计算机仿真比较，结果表明：Chen-Mobius通信系统具有抗强噪声的性能，在噪声中可以很好地恢复图像信号，其还原成数字图像效果优于传统通信系统．

On basis of the Mobius transforms, the method of modulation and demodulation in Chen-Mobius communication systems, which is quite different from the traditional one,is applied in the image transform. To make such a processing,the Chen-Mobius inverse transformed functions act as the ＂modulation＂ waveforms, and the receiving end coherently ＂demodulated＂ by the often-used digital waveforms. In additional, the image transform is simulated by the MATALAB software on the computer and the results are discussed in some detail. It shows that the new application has excellent performances that the digital image signals can be restored from intense noise.
