| 摘 要： | 红外图像数据传输时，由于数据量大，需压缩后传输，而压缩后数据对信道干扰非常敏感，需进行信道纠错编码以保障数据传输，提高抗干扰性。本文介绍了一种信源信道联合编码策略，即信源采用多分辨率重采样图像压缩算法，信道采用RS码加交织，解决了图像传输过程中的信道干扰问题。

| Abstract: | Because of the bulk data in infrared image transmission, compression is required. The compressed data is sensitive to channel interference, where then the channel error correction coding is introduced to enhance the channel anti-jamming characteristics. To overcome it, this paper presents a source-channel combined coding scheme, in which both multi-resolution over-sampling is used for source coding and RS and interleaver coding is used for channel coding. |

| Keywords: | Joint source and chnnel coding image compression Reed-Solomon code Interleaver |
