adaptive coder 解釋
自適應編碼器
  1. Large - alphabet chinese text compression using adaptive markov model and arithmetic coder

    使用調適馬可夫模型與算術編碼之大字符集中文文本資料壓縮
  2. Context based adaptive arithmetic coding is used in the last part of the encoding process as the entropy coding. the mq coder is adopted in jpeg2000

    與其它的熵編碼方法相比，算術編碼能夠取得更好的壓縮效果，但它演算法復雜，運算量相對增加。
  3. People often think about the filter ' s characters of orthogonal, symmetry, regularity, but seldom synthetically think about some factors such as image texture or compression rate. in this paper used the same adaptive arithmetic coder for many filters, analyzed the effect factors synthetically for the best wavelet compression, and give some methods for selecting filter

    本文對多種常見濾波器，採用相同的自適應量化編碼方法進行實驗，研究並分析了選擇濾波器時應該考慮的圖像紋理、濾波器長度、壓縮比等一些綜合因素，有效解決了在小波圖像壓縮過程中，如何更好的選擇濾波器的問題。
  4. Subjective testing indicates that the quality of cs - acelp is equivalent to that of the 32kbit / s adaptive differential pulse code modulation ( adpcm ) under error - free conditions and it outperforms g. 726 under error condition. in this paper, standard c is adopted in realization of the algorithm, presents program strategies and steps of algorithm of each module. the coder and decoder is tested by utterances with noise

    用標準c語言模擬實現了該演算法，計算了mos分值，女聲： 4 . 180497 ，男聲： 4 . 199782 ，並在相同的測試語句中加入噪聲進行測試，含噪語句通過該編解碼器，輸出的合成語音用主、客觀評價標準評價，與原始不含噪語音效果差別不大，平均mos分值為：女聲4 . 1375 ，男聲4 . 1668 ，說明該演算法是優秀的編解碼演算法。
  5. This paper first research on main technologies used by avs standard, which include prediction, transform, quantization, in - loop filter, and entropy encoding, and then focus on the 2d - vlc entropy coder of avs, which is context - based adaptive coder. this encoder operates on run - level pair, and it uses the type of current block and value of current coefficients to switch vlc code - table. these tables are designed according to the distribution of transformed coefficients, and this way is much better than using only one table to code all residual coefficients in one 8x8 block

    本文首先詳細研究了avs標準的核心技術，包括預測編碼、變換量化、環路濾波器以及掃描和熵編碼等，之後重點研究了avs標準中使用的基於上下文的2d - vlc變長編碼方法，這種方法編碼的是（ run ， level ）數對，同時根據當前編碼塊的類型和殘差系數這兩種上下文信息來切換碼表，這些碼表是預先根據變換系數在不同位置的分佈信息設計好的，這樣要比只使用一個變長碼表來編碼塊內所有位置上的殘差系數的壓縮效果要好得多。
  6. The approach in this thesis first design the best performance channel code in different channels and different snr, then design the adaptive coder / decoder. the receiver continually estimates the fading and noise of the channel and transmits them to the transmitter by reverse channel. then the transmitter use these information to choose the best channel code adaptive the current channel

    本文提出的自適應調制方案首先設計各種通道衰落和信噪比條件下的最優通道編碼，再設計一種能夠完成這些通道編碼解碼的自適應編碼解碼器；接收機不斷估計通道的衰落程度和噪聲功率，並通過反向通道反饋給發射機；發射機據此選用最適合當前通道的通道編碼，實現自適應。
