RPE-LTE下的GSM全速率语音编解码功能，显示编码前后语音波文件的波形变化。
INSTRUCTIONS:
- run MAIN_relp.m
- copy your desired file in this folder and write the filename
in MAIN_relp.m and run it.
INFO:
This is a simulation of Regular Pulse Excited Long Term Predictor used in
GSM 6.10. These codes have been written for simulation purposes only and
it hasn't been generalized yet for wavfiles sampled at any frequency. It
has been temporarily done only wavfiles with 8000 Hz sampling frequency.
Also that quantization effect hasn't been added yet. The codes will be
updated soon. We appolagize for the temporary inconvenience.
