scrambling coding 解釋
保密編碼
  1. Our object is an intermediate frequency modem of a software defined radio transmitter - receiver of multi - service, multi - modulationmode and multi - processdatarate. first, related software defined radio theory is introduced ; later, channels of transmitter - receiver are designed with consideration of data format, modulation, fec, interwaving. and scrambling ; emphasis is placed on theory and implementation of an audio compression algorithm cvsd ( continuous variable slope delta modulation ) and a fec technique convolutional coding - decoding

    本文首先介紹了相關的軟體無線電理論;然後完成了包括數據格式,調制方式,糾錯碼方式,交織器和擾碼器等部分的中頻數據機通道設計;接著著重介紹了系統中使用的音頻壓縮演算法cvsd (連續可變斜率增量調制)的原理和實現,以及作為前向糾錯碼的卷積碼編碼理論和編解碼的高效實現。
