"3GPP EVS RTP传输协议解读与AMR-WB互操作模式分析"。

The document "26445-g11_a_s0608_sHistory.doc" is a technical document sourced from 3GPP regarding the EVS RTP transmission protocol. Specifically, it outlines the interoperable modes for AMR-WB in section 6.8. The section delves into the decoding and speech synthesis process for the AMR-WB-interoperable modes. The decoding process begins with the reconstruction of the quantized ISP vector using received indices of ISP quantization. Subsequently, interpolation techniques are employed to generate 4 interpolated ISP vectors corresponding to 4 subframes. These interpolated ISP vectors are then converted to LP filter coefficient domain for each subframe. Overall, this document provides detailed insights into the technical aspects of decoding and speech synthesis for the AMR-WB-interoperable modes, emphasizing the importance of accurate reconstruction and interpolation techniques in the process.
