话音瞬时值与有效值在信噪比计算中的应用齐齐哈尔铁路运输职工大学陈国通在数字通信中，传统的语音量化信噪比的计算，都是用话音在编码之前的均方根值与过载值之比作为动态值来考虑各抽样的信噪比。我认为不切合实际，本文将分析量化噪声及信噪比（ＳＱＲ）计算中的几个... The application of voice instantaneous value and effective value in signal-to-noise ratio calculation Qiqihar Railway Transportation Workers College Chen Guotong In digital communication, the traditional calculation of speech quantified signal-to-noise ratio is the use of voice before coding root mean square and overload values Ratio as a dynamic value to consider the signal to noise ratio of each sample. I think it is not practical, this article will analyze the quantization noise and signal-to-noise ratio (SQR) calculation of several ...
