時間編碼-
On the base of researching the theory of the scheme and analyzing the signal feature, it is obtained that the existence manners and character of distance information in the differential frequency signal. at the same time, a new conclusion is gained that the technology of frequency agility can decrease the constant error of system. it is also to say that frequency agility and frequency modulation fixed - distance fuze has the similar feature to random period frequency modulation fixed - distance fuze. according to the theory of address coding in the hopping - frequency communication, the paper presents the principle of selecting the frequency agility sequence which fit to the radio fuze and constructs the frequency agility sequence family based on the rs codes
在深入研究方案原理和分析信號特徵的基礎上，獲得了該體制引信差頻信號中，距離信息的存在形式和特點，得出了頻率捷變技術的引入降低了系統定距固定誤差這一新的結論，即頻率捷變調頻定距引信在定距性能上具有類似隨機周期調頻定距的特徵。本文引入跳頻通信地址編碼理論，結合無線電引信的具體特徵，提出了適用於無線電引信的頻率捷變序列的選擇原則，並構造了基於rs碼的寬間隔頻率捷變序列族。 -
It is well known that jpeg and jpeg2000 are still image compression standard with high performance at present time. so we choose them as our investigative base to compress image. my amendment in jpeg mainly includes self - adaptive huffman coding and reduction of blocking effect
由於jpeg標準所提供的演算法還有進一步改進的可能，所以在文中將介紹如何對jpeg標準進行演算法改進，主要包括：自適應哈夫曼編碼、塊效應的消除；針對jpeg2000標準，將主要介紹jpeg2000標準核心演算法的實現以及如何用最大位平移方法實現感興趣區編解碼。 -
Then describe three aspects of the key techniques of using linux as the development tools of embedded system including the real - time variant of linux ? ? rt linux and it ' s principle, implementation and the programming ; the network coding in linux kernel and the analysis of linux network device drivers and the online debug environment of linux kernel and rtlinux kernel. i have also involved the implementation of embed linux / rtlinux in a floppy to simulate the embedded environment. in the last part of this thesis, i give the suggestions and prospect of the development of a mature embedded system which have the most competition ability in china market base on the current work
緊接著，分兩個方面論述使用linux進行嵌入式系統開發的便利，包括linux的實時變種? ? rtlinux的原理、實現方案和編程方法，並且編程實現了一個計算實時任務調度時間的軟體； linux網路設備驅動程序的分析和利用到嵌入式系統中的方案；然後，以作者在黑龍江傲立信息有限公司課外實習期間的實際工作經歷，介紹了基於lineo公司的ucsimm開發評估板進行嵌入式設備開發的一般過程。 -
There are two research works is involved in this thesis. first, an algorithm of data reconstruction in videos and images is proposed. base on this reconstruction technology, we developed the precept of layer coding in sender, the structure of data stream and the precept of post processing in receiver with analyzing the scheme of real time transmission of video in network
本文的研究工作包括兩個方面：首先提出了一種視頻與圖像中數據丟失的重建演算法，以此為基礎對基於網路的實時視頻傳輸方案進行了研究，提出了信源端分層編碼方案、數據流組織方案以及接收端後向處理方案。
