Latest Patents

Liu's latest patents include a "Method for piloting from bypass in a network based on satellite load platform." This method addresses the challenges posed by distance changes and Doppler frequency shifts in satellite ground stations, enabling accurate quasi-synchronization between the network's clock and the satellite's clock. The process involves transmitting a pilot signal from a bypass based on a satellite load platform, utilizing a spaceborne high stability timing clock source as a reference. This pilot signal is then sent to all downlink beams, ensuring synchronization across all satellite stations covered by the satellite.

Another notable patent is the "Method for quasi-synchronous code division multiple access based on synchronization clock by piloting." This method allows CDMA to operate under quasi-synchronous conditions, making it suitable for open wireless channels with or without relay nodes, such as satellite communication systems. The approach employs CDMA spread spectrum transmission to share power resources among multiple transmitting stations, while an external pilot signal provides synchronization for the CDMA signals, eliminating path delay differences and achieving synchronized reception of multi-channel CDMA signals.
