First the predefined signal is to be detected by each of the sensors and its time frame boundary information is acquired by a detector. The detector is composed of a matched filter bank, an event detector and a state sequence detector. The phase error is derived with reference to a fixed reference stored. With each of the sensors updating its local clock to the same fixed reference they can be brought to an arbitrary close clock error with one another. Thus, by applying the method disclosed here the transmitter and all the receivers can have an arbitrary small clock rate error with respect to one another. The method described is really fast in the sense that the delay needed for the detection and adjustment is minimal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method to estimate and compensate for clock rate difference in acoustic sensors","description":"A predefined signal has been used to facilitate the detection of the clock rate difference between the transmitter and the receiver.
