摘要
对DCME (数字电路倍增设备 )中的传真解调、再调制技术进行了研究 ,对基于ITU TV 2 9建议的 960 0bit/s传真信号提出了一个全数字调制解调器模型 ,并给出了算法。在调制部分采用了符号成形法 ,较好地解决了频谱混叠的问题 ,该算法计算量小 ,具有较好的性能 ,易于DSP (数字信号处理器 )实现。
This paper mainly discuss the technology of facsimile demodulation and remodulation An all digital demodulation/remodulation model and its algorithm are given in this paper A method of symbol shaping is used to solve the problem of frequency overlap From simulation result, this model is proved a good performance and less computation
