Latest Patents

Fei Yu holds a patent for a "Timing response-based clock frequency offset estimation method for industrial wireless sensor network." This invention relates to a method for estimating clock frequency offsets based on timing responses. The method involves sending a data packet from a node to be synchronized to a reference node. After receiving the data packet, the reference node replies with an acknowledgment after a timing response interval, which is mapped according to the sequence number of the data packet. Through multiple interactions, the node can estimate a relative frequency offset and a fixed delay between node clocks without exchanging timestamp information. This innovative approach reduces communication overhead and energy consumption while enabling long-term tracking of clock frequency offsets with low computational costs.
