binary coded information

基本解釋

First, secret speech is coded into binary parameter bits with Mix-Excitation Linear Prediction (MELP) algorithm, and the bits are arranged to form hiding information sequence.
首先將保密語音經(jīng)混合激勵線性預(yù)測（MELP）編碼和糾錯編碼形成隱藏信息。
Then, we introduce the principle and application of density evolution (DE) and extrinsic information transfer (EXIT) chart technology for the analysis and design of binary LDPC coded modulation.
然后介紹了用于二元LDPC碼分析和設(shè)計(jì)的密度進(jìn)化和外信息轉(zhuǎn)移圖技術(shù)的原理及應(yīng)用。
