CVSD ( Continuous Variable Slope Delta(CVSD) 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。
Three kinds of speech encoding schemes, namely, Pulse Code Modulation, A law PCM and Continuous Variable Slope Delta(CVSD) Modulation, are discussed mainly. 主要讨论了三种语音编码方案,即线性脉冲编码调制(PCM,PulseCodeModulation)、A律PCM和连续可变斜率增量调制(CVSD,ContinuousVariableSlopeDeltaModulation)。
Meanwhile, this paper also refers to the Continuous Variable Slope Delta(CVSD) Modulation ( CVSD ) voice coding algorithm, which is adopted in the transceiver. 同时对该设计中采用的CVSD语音编码算法作了简要介绍。
