基于DSP的16路全双工来电号码分析与实现(英文)

16-Channel Full Duplex Caller ID Realization with DSP

作者介绍了根据v.23协议实现16路全双工来电号码分析和显示的原理,FSK的算法设计及基于DSP的软硬件设计,讨论了系统在实践中抗干扰性的预防和高精度检测方法的应用.该系统已开发成功并投入了使用.

Calling ID(CID) detection is widely required in both public and private life. The authors introduces the analysis of 16-channel full duplex CID information, the algorithm design of FSK, and the realization of CID system based on DSP. The authors also discusses the prevention of the interference immunity of CID system and the techniques of high precision detection. The CID system has been developed successfully and come into service.
