Optimization blind processing algorithm for high frequency signal of capacitive sensor

摘要

In the process of blind processing for high frequency signal of capacitive sensor, because of the high frequency signal, the anti-interference ability and the real-time feature of the blind processing are poor. Thus, in this paper, a real-time blind processing method for high frequency signals of capacitive sensors is proposed. In the real-time separation process of hybrid blind signal of capacitive sensor, the high frequency signal of capacitive sensor is made bleaching treatment, to remove the correlation between hybrid signals, and combining the wavelet packet frequency hopping, the signal blind processing is realized. Experimental results show that this method can effectively improve the accuracy of blind processing for high frequency signals of capacitive sensor.
