Recently , mobile code technology has a great deal of development and promises well . however the security problem with mobile code technology obstructs its wide application in real business 近年来，移动代码技术得到了极大的发展，并有着广泛的应用前景，但代码移动性所引发的安全问题阻碍了该技术在现实商业应用中的大规模使用。
With the development of digital communication and multimedia technology , the research on very low bitrate video coding technology is becoming more important . this thesis mainly studies the low bitrate video coding based on h . 263 standard 随着数字通信和多媒体技术的发展，极低码率视频编码技术的研究变得尤为重要。本文主要对基于h
It is not enough to only apply wavelet analysis for utmost improving compression ratio in the premise of keeping compressed image good sight . for this destination , it also need rely on some coding technologies 为了在保持压缩图像视觉效果的前提下，最大限度地提高图像压缩比，单纯借助小波分析是不够的，还必须依靠一定的图像编码技术。
This paper discusses the possibility of using phase - coded technology in the long distance radar , which mainly faces the problem of signal sidelobe in the large dynamic range , and the problem of getting along with the phased array technology 本文讨论将相位编码雷达用于远距离观测雷达上的可能性，主要需考虑大动态范围下信号旁瓣影响问题及相控阵处理融合问题。
Low - density parity - check codes come to be one of the best coding technologies because of their low - complicity iterative decoding algorithm and capacity approaching performance , and they attract more and more researchers " eyes in recent years 低密度校验码以其低复杂度的迭代译码算法和可逼近信道容量限而成为目前最佳的编码技术之一，越来越受到众多编码研究学者的关注。
