摘要
介绍了传真调制解调标准ITU-T V.29,分析了用纯软件的方法实现调制解调的特点和关键技术,给出了一种基于TMS320C6201定点DSP的实现方案。该方案可以完全实现V.29各项功能。
This paper describes an implementation of soft modem of ITU-T V.29. First, a brief view of the ITU-T V.29 is given. Then the comparison between the traditional QAM receiver and the soft modem is carried and the key techniques are pointed out. At last, a practical structure for the V.29 soft modem is presented and each module is examined.
