摘要
DTMF拨号音的识别在通信领域有着重要的地位和作用。从基本概念着手,阐述了DTMF的编码、检测及解码原理,介绍了一种基于TMS320C5402实现对通话数据中DTMF拨号音进行检测和解码的方法。在性能分析的基础上得出了实际应用中很好的检测效果。
The identification of DTMF Tone plays an important role in communication area. Entering on the basic conception, the theory of DTMF tone's encode, detection and decode is specified. A method to implement them based on TMS320C5402 is introduced. At last, a perfect effect in practical application is drawn on the basis of performance analysis.
