摘要
介绍了如何将判决反馈QAM载波恢复环技术、峰值检测法用于DCME(DigitalCircuitMultipli cationEquipment,数字电路倍增设备)传真解调中的载波恢复和定时提取,并在此基础上提出了改进的联合解调算法。
This paper mainly discusses how to apply decision feedback QAM carrier recovery loop to carrier recovery and apply peak value detection method to timing extraction in DCME facsimile signal demodulation. An improved joint demodulation algorithm is also presented.
