ITU-T G.728语音压缩算法的实时实现

Real-time Realization of ITU-T G.728 Speech Compression Algorithm

ITU -TG .72 8建议是国际电信联盟于 1992年制定的比特率为 16kb/s的低延时CELP类语音编码器。在扼要介绍G .72 8编解码算法原理基础上 ,详细讨论了G .72 8的LD -CELP算法在TMS32 0C6 2 11上实时实现的硬件设计和软件开发及系统设计中的一些关键技术。

ITU - T G.728 recommendation shows a low-delay speech coder at the bit - rate of 16kb/s, which is a kind of EELP speech coder and was worked out by the international Telecommunication Union in 1992. Based on a brief introduction to code-decode algorithm principles, this paper discusses, in detail, the real-time realization hardware designing and software development of LD-CELP algorithm of G. 728 on TMS320C6211 and the key technology in the design of system.
