codebook

基本解釋

This method utilizes VQ and LBG algorithm to design the codebook.
該方法使用了向量量化技術(shù)并采用LBG算法設(shè)計(jì)碼本。
This algorithm has a small complexity and no codebook is needed.
該算法計(jì)算簡(jiǎn)單，無(wú)需碼書存儲(chǔ)。
Ciphers are more convenient than codes in some situations, there being no need for a codebook.
有些情況下，“密碼”比“編碼”更方便，因?yàn)椤懊艽a”無(wú)需反復(fù)查詢密碼本。
In this theory，all codewords in codebook are rotated to four hieratical directions to check their correlations.
提出了將碼書中的碼字旋轉(zhuǎn)壓縮的理論。
One is the robustness against channel noise;the other is the computational complexity of codebook search.
第一個(gè)是增加向量量化的抗雜訊能力，另一個(gè)則是減少碼書搜尋的復(fù)雜度。
