- 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碼付諸于實際的應(yīng)用還存在問題，衰落信道譯碼的研究正是在turbo碼的實際應(yīng)用上所提出的問題。 - 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是國際電信聯(lián)盟新頒布的編碼速率為8kb s的低速率語音壓縮編碼標(biāo)準(zhǔn)，它是基于ip網(wǎng)絡(luò)的多媒體會議系統(tǒng)標(biāo)準(zhǔn)h 323可選的語音壓縮編碼標(biāo)準(zhǔn)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
論文的第四部分，針對可視電話中最耗費計算時間，也是其中最關(guān)鍵的技術(shù)? ?離散余弦變換( dct )和運動估計算法進(jìn)行的仔細(xì)的研究，分析了當(dāng)前出現(xiàn)的經(jīng)典的實用算法，并對其原理進(jìn)行了研究和介紹，并總結(jié)各種算法的特點和原理，各自提出了其的改進(jìn)算法，給出了其原理介紹和實現(xiàn)方法，并在計算機(jī)上使用c語言進(jìn)行了仿真試驗，并達(dá)到了較為滿意的效果，這兩種算法，完全可以通過硬件得以實現(xiàn)并能應(yīng)用到實際的可視電話的視頻模塊壓縮算法中去。
