Estimating maximum codeword lengths of discrete data compressing 離散數(shù)據(jù)壓縮的最大字長估計
A new type of two - dimension codeword structure of ocdma system and it ' s realization method 型三角剖分上的雙周期三次樣條函數(shù)空間
The experiment shows the improved algorithm can search codeword faster and effective 仿真實驗表明此改進算法能快速有效地搜索碼字。
The classical algorithm of vq codebook design ? lbg algorithm and traditional codeword search algorithms are reviewed 回顧了經(jīng)典的矢量量化碼書設(shè)計算法? ? lbg算法和傳統(tǒng)的碼字搜索算法。
One special address codeword which is a “ 0 / 1 ” sequence of certain code - length is assigned to each user in advance 在ocdma系統(tǒng)中,每一個用戶預(yù)先被分配一個特定的地址碼,即一個字長的0 / 1序列。
2 . three criteria for evaluating performance of interleaver , ie . , the codeword weight decision , correlation analysis and iterative decoding suitability ( ids ) , is proposed 2 、提出了交織器的碼重分析、相關(guān)性分析和交織器迭代譯碼的適應(yīng)性( ids )三種性能判別和分析方法。
This he did at least 13 times . “ de lesseps ” , it turned out , was the codeword for the egyptian army to start the seizure , and nationalisation , of the canal 他至少13次提及萊塞普這個名字,后來的事實說明,這個名字就是埃及軍隊開始奪取蘇伊士運河控制權(quán)的代號,同時也是運河國有化的代號。
The traditional codeword search algorithm ? full algorithm ( fs ) has a serious disadvantage , whose computation quantity will rise sharply with the increase of the codebook size and the codeword dimension 傳統(tǒng)的碼字搜索算法? ?窮盡搜索算法會隨著碼書規(guī)模的增大和碼字維數(shù)增加,計算量急劇增加。
Vector quantization can be used to take advantage of the correlation between neighboring pixels by quantizing pixels in groups ( or vectors ) rather than individually and symbolically representing the vector with a codeword 本文就是從矢量量化技術(shù)的研究入手,開發(fā)它在圖像壓縮上的應(yīng)用。并借助于并行計算技術(shù)來加快處理過程。
Second , we optimize the codebook and choice a part of the codeword which is used most efficiently . the result is not degraded too much while the complexity is reduced . at the end of the paper the development prospect of cs - acelp and speech coding are described 對lsp參數(shù)量化中的第一級碼書的128個碼字的使用頻率進行了統(tǒng)計試驗,選用了128個碼字中使用頻率高的112個碼字作為新碼書,語音質(zhì)量基本不變但降低了碼書搜索的復(fù)雜度。
