摘要
ITU-T提出基于CS-ACELP算法传输速率为8 kbit/s的G.729协议,该协议可以用作如PHS(个人手持电话系统)、比特率低于64kbit/s的可视会议等多媒体服务,也可以作为有效利用传输能力的多路复用器。概要介绍了G.729协议的算法结构,对G.729协议在TMS320C6211DSP上的实现进行了研究。
In 1995, coding of speech at 8kbit/s using CS_ACELP was standardized as recommendation G.729. It is expected to be used for such multimedia applications as PHS (Personal Handy - phone System) service, desktop conference at bit rates below 64kbit/s, and multiplexers for effective use of transmission capacity. This paper introduces the algorithm structure of G.729 and performs this recommendation on TMS320C6211DSP.
