Lc apparatus almost meet all the needs of space optical communication such as weight, size, power consume, life, cost, driving voltage, intergration of optics and electricity, programe, optically take ? over aperture, beam scanning, deflexional range and so on. switches, deflexional facilities and scanning equipments which made with lc have been used in the system of labor in space communication. the only bug of lc apparatus is that their answer speed only get microsecond rate or submicrosecond rate. but it is practical for them to be used in special beam capture, scan, deflexion controling which don ’ t concerned with code rate and code type
液晶器件幾乎滿足空間光通信的所有大的指標要求如重量、尺寸、功耗、壽命、成本、驅動電壓、光電集成、可編程性、光學接收孔徑、光束掃描和偏轉范圍等等。液晶光開關、光偏轉器、光掃描器已經開始應用於光纖通信的實驗系統中。液晶類器件應用於光通信的唯一重大缺陷,是其響應速度目前只能達到微秒級或亞微秒級,不過,在不涉及到碼型碼率的空間光束捕獲、掃描、偏轉、控制方面,液晶器件完全可能進入實用化。Information technology - digital compression and coding of continuous - tone still images - registration of jpeg profiles, spiff profiles, spiff tags, spiff colour spaces, appn markers, spiff compression types, and registration authorities regaut
信息技術.連續色調靜態圖象的數字壓縮和編碼. jpeg提問文件, spiff提問文件, spiff標識符, spiff顏色空間, appn標記, spiff壓縮型和注冊權威機構We put the emphases on the soft output viterbi algorithm ( sova ), which is one of turbo code ’ s decoding algorithms, and presents the derivation and computation step of the sova decoding algorithm. after presenting sova and map decoding algorithms and analyzing four kinds of decoding algorithms, the paper makes a comparison among the different decoding algorithms by emulation analysis, and analyzes the time complexity of various algorithms, and then contrasts them. in the last part of this paper, according to the criterion recommended by the consultative committee for space data systems ( ccsds ), including code rate,
根據空間數據系統顧問委員會( ccsds )為turbo碼應用於深空通信系統推薦的標準,包括碼率、碼塊大小、分量碼類型、約束長度、碼生成多項式,以及交織器的選擇等參數的建議以及sova譯碼演算法的理論基礎,設計了sova演算法的實現結構,通過模擬驗證了本文所採用的turbo碼的性能,從而證明turbo碼確實是一種很好的通道糾錯編碼方式,它適用於要求功耗低或信噪比低的深空通信系統中。3. in order to improve searching quality of restricting optimization, good and bad gene code method has been brought forward. its focus lays in emphasizing the value of gene to targets and more precisely simulate evolvement mechanism so that useful information in problem space will be used completely
為提高約束優化的搜索質量,提出了基因優劣編碼,其重點是精確模擬自然進化機制,著重強調各基因位對優化目標的價值作用,越有利於優化目標的基因位越有價值,從而使問題空間的有益信息得到了充分利用。Based on the analysis of image wavelet transformation and the space / frequency distributing characteristics of different subbands " coefficients, this dissertation fully exploits the following theories and methods : scalar quantization, vector quantization, trellis coded quantization, trellis coded vector quantization, vector classification, codebook expansion and weighted mean square error rule basing mankind visual characteristics, etc. from different angles of information amalgamation, it develops several innovative algorithms of image compression and coding, gives their realization schemes, and makes plentiful simulation tests
