语音编码方案的选取对移动通信系统的通话质量、信道容量等有重要影响。本文讨论了TD-SCDMA系统中AMR语音编码的自适应机制,同时分析了AMR中代数码本线性预测(ACELP)算法及实现过程。该方案可以在一块TMS320C5510上实现。(The selection of voice coding schemes for mobile communication systems the quality of the call, such as channel capacity have had a significant impact. In this paper, TD-SCDMA System AMR Adaptive speech coding mechanism, at the same time analysis of AMR in the generation of Digital Linear Prediction (ACELP) algorithm and the realization of the process. The program can be achieved in a TMS320C5510.)
