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)混郃激勵線性預測（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.
然後介紹了用於二元LDPC碼分析和設計的密度進化和外信息轉(zhuǎn)移圖技術的原理及應用。
