摘要
文章参照3GPP TS协议,对于自适应多速率(AMR)语音编解码算法进行了深入的研究,并且对其工作原理做了详细的分析。然后,在阐述AMR编解码器各部分完成的功能和具体算法的基础上,以TI公司的TMS320VC5510 DSP和TLV320AIC1107芯片为核心,搭建起硬件实验测试平台,并对编码算法进行测试,取得了满意的效果。
This paper, referring to 3GPP TS, gives an in-depth study on AMR, and carries out a detailed analysis on the working principle of AMR. Then, based on the discussion of functions and arithmetics accomplished by each part of AMR, and taking TMS320VC5510 DSP and TLV320 AIC1107 from Texas Instruments as the core, a hardware experiment-testing platform is thus built up. And the test on the coding algorithm has achieved satisfactory results.
