在传感器，特别是分布式光纤传感器领域，原始信号通常具有微弱性、周期性等特点，在经过接收电路后会出现不可避免的失真，对后续的信号处理带来极大的影响。在对微弱周期信号接收电路进行理论分析的基础上，提出一种基于微弱周期信号的自适应处理算法，采用该算法对接收信号进行数据处理可以显著降低输出信号的失真度，实现了对输出信号进行优化、补偿的一种通用处理方法。
在傳感器，特彆是分佈式光纖傳感器領域，原始信號通常具有微弱性、週期性等特點，在經過接收電路後會齣現不可避免的失真，對後續的信號處理帶來極大的影響。在對微弱週期信號接收電路進行理論分析的基礎上，提齣一種基于微弱週期信號的自適應處理算法，採用該算法對接收信號進行數據處理可以顯著降低輸齣信號的失真度，實現瞭對輸齣信號進行優化、補償的一種通用處理方法。

In the field of sensor, especially distributed fiber sensor, the primary signal has the characteristics of weakness and periodicity. After passing through the receiving circuit, the signal is distorted unavoidable and the following signal processing will be influenced greatly. On the basis of theory analysis of the receiving circuits of weak and periodic signals, a self-adaptive processing algorithm based on weak periodic signal is proposed. The algo-rithm is used to process receiving signals so that the distortion of output signals is reduced greatly. A common pro-cessing method for optimizing and compensating output signals is realized.
