一种信号处理方法、节点和装置制造方法及图纸

本发明专利技术公开了一种信号处理的方法，适用于通信技术领域。方法包括：接收光信号，将所述光信号转化为电信号，再转化为数字信号；从所述数字信号中提取左以及右边带导频，计算左边带导频的功率以及右边带导频的功率，根据所述左边带导频的功率的和以及右边带导频的功率的和计算得到鉴相信息；将所述鉴相信息插入待发送的光信号中，发送所述插入所述鉴相信息的光信号。本发明专利技术实施例通过插入导频，然后通过功率函数计算左边带导频的功率以及右边带导频的功率，根据所述左边带导频的功率的和以及右边带导频的功率的和计算得到鉴相信息，得到的鉴相信息能够准确反映第二节点发射信号的频偏，使得第二节点能够准确地调整发射信号的频率。

A signal processing method, node and device

The invention discloses a method of signal processing, which is suitable for the field of communication technology. The method comprises: receiving the optical signal, the optical signal into electrical signals, and then converted to digital signals; the left and right with pilot extracted from the digital signal, power calculation on the left with the pilot power and right with the pilot, according to the power of the pilot and the left and right with the pilot and the calculated phase information; optical signal will be inserted into the phase information to be sent, sent by the insertion of the light signal phase information. The embodiment of the invention by the pilot, and then take the pilot power through power function calculation on the left with the pilot power and the right, according to the power of the pilot and the left and right with the pilot and calculate the phase information, the phase information can reflect the second the node transmission signal frequency offset, the second node can accurately adjust the frequency of the transmitted signal.
