远程控制设备和系统.第1 - 5部分:概论.带有扰码器的调制解调器传输程序对使用协议iec 60870 - 5的传输系统的数据完整性的影响
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
本文首先介绍了相关的软件无线电理论；然后完成了包括数据格式，调制方式，纠错码方式，交织器和扰码器等部分的中频调制解调器通道设计；接着着重介绍了系统中使用的音频压缩算法cvsd (连续可变斜率增量调制)的原理和实现，以及作为前向纠错码的卷积码编码理论和编解码的高效实现。
