连续可变斜率 meaning in English

cvs continuously variable slope

Cvsd （ continuous variable slope delta modulation ） voice coding enables operation at high bit - error rates
连续可变斜率增量调制的语音编码可以在高误码率的情况下正常工作。
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。
