GSM_HR 半速率 语音编解码
完成GSM_HR语音编解码器的测试功能 /************************************************************************ European digital cellular telecommunications system 5600 bps speech codec for half rate speech traffic channels Bit-Exact C Simulation Code Version 10.0.0 Original created on November 8, 1996 *************************************************************************/ These files represent the Half-Rate GSM Speech Coder Bit Exact C simulation. All code is written in ANSI-C. The system is called from a single program named "gsm_hr" which can operate in one of two modes: (0) encoding only (1) decoding only For encoding, the input is a binary speech file (*.inp) and the output is a binary encoded parameter file (*.cod). For decoding, the input is a binary parameter file (*.dec) and the output is a binary synthesized speech file (*.out). Note that the format for the parameter input file required for decoding (*.dec) is not the same as the format of the parameter file generated by encoding (*.cod). The "reid" program will translate an *.cod file into an *.dec file (select error-free mode, EP0).
