Description: 长期预测(LTP)与规则脉冲激励(RPE),而全速率编解码器就被称为RPE-LTP线性预测编码器。
输入至RPE-LTP编码器的数据为包括160个采样值的20ms语音,每一个采样值都拥有13位精度。数据首先通过预加重滤波器来提高信号的高频分量,以获得更好的传输效率。滤波器一般还消除信号上的任何偏移以简化进一步的计算。
正如前面所提到的,语音产生模型可看成是空气通过一组不同大小的圆柱体。短期分析级采用自动相关来计算与模型所用的8个圆柱体有关的8个反射系数,同时采用一种称为Schur递归的技术来有效地求解所得到的方程组。参数被变换成可以更少的位数来进行更佳量化的LAR(log-area ratio)。这些是传输流的前8个参数。
然后再将编码后的LAR解码成系数,并用来对输入采样值进行滤波。解码LAR的原因是为了确保编码器使用解码器上的相同信息来进行滤波。这一级上的其余采样值用于编解码器的LTP级。

Description: The low level speech compression algorithm of the GSM suite is called GSM 06.10 RPE LTP (Regular Pulse Excitation Long Term Predictor). My colleague Dr. Carsten Bormann and I have implemented a GSM 06.10 RPE LTP coder and decoder in C. Its source code is freely available, and we encourage you to use it, play with it, and invent new real time media protocols and algorithms.
Our implementation consists of a C library and a stand alone program. Both are destined to be compiled and used on a Unix like environment with at least 32 bit integers, but others have ported it to VMS and a MS DOS 16 bit environment. GSM 06.10 is faster than code book lookup algorithms such as CELP, but by no means cheap to use it for real time communication, you will need at least a medium scale workstation. -The low level speech compression algorithm of the GSM suite is called GSM 06.10 RPE LTP (Regular Pulse Excitation Long Term Predictor).
