| 摘 要： | 数字图像经过压缩编码后通过无线信道传输,必须考虑信道中各种噪声对编码数据的影响。文中首先介绍了两种常见的无线信道模型,并对其传输特性进行了总结,然后分析了JPEG2000的编码原理,重点对其在带有高斯白噪声信道下的容错性进行了研究。实验结果说明,JPEG2000的抗干扰性能要优于传统的图像压缩标准。

| Abstract: | Compressed digital image bit-stream transmitted over wireless channel must consider the effects of the channel noise.In this paper,we first introduce two wireless channel modes,the transmission characteristics of which are discussed.The code principle of JPEG2000 as well as its error resilience in AGWN fading wireless channel are analyzed.Experiments results demonstrate that JPEG2000 performs better anti-jamming capability than the traditional still image compression standard. |
