Examples
- As an optional code of 3g , the research of turbo code is significant . its performance over rayleigh channel is just to solve the practical problem
而turbo码付诸于实际的应用还存在问题，衰落信道译码的研究正是在turbo码的实际应用上所提出的问题。 - The g729a , a new issued speech compressed coding standard at 8kbit / s , is one of the optional coding standards of h . 323 , which is multimedia meeting system standard based on ip network
729a是国际电信联盟新颁布的编码速率为8kb s的低速率语音压缩编码标准，它是基于ip网络的多媒体会议系统标准h 323可选的语音压缩编码标准之一。 - The paper introduces the technique of the recommendation on the basic frame , encoder and decoder ' s main technique and regulation , the syntax and semantics of the bitstream , optional coding algorithm , and etc . in the forth part of the paper , aimed the time - costest and most important technique - discrete cosine transform ( dct ) and motion estimate algorithms , paper analyses the classical and practical algorithms and introduce the theory . then paper sum up all the algorithms character , give out the ameliorated algorithm , and simulate with the c language on the computer . these two algorithm , can be realized using hardware and can be used into the real videophone ' s video module
论文的第四部分，针对可视电话中最耗费计算时间，也是其中最关键的技术? ?离散余弦变换( dct )和运动估计算法进行的仔细的研究，分析了当前出现的经典的实用算法，并对其原理进行了研究和介绍，并总结各种算法的特点和原理，各自提出了其的改进算法，给出了其原理介绍和实现方法，并在计算机上使用c语言进行了仿真试验，并达到了较为满意的效果，这两种算法，完全可以通过硬件得以实现并能应用到实际的可视电话的视频模块压缩算法中去。
