本文介绍了语音通信系统中LPC和CVSD的串接原理和具体方案,其中包括数字域内CVSD-LPCM之间的直接转换以及信号抽样率的升高和降低(插值与抽取),并还说明了改善串接系统性能的一些方法。
This article describes the cascaded principle and specific solutions for LPC and CVSD in a voice communication system, including the direct conversion between CVSD-LPCM in the digital domain and the increase and decrease (interpolation and decimation) of the signal sampling rate, and also illustrates the improvement Some methods of concatenating system performance.
