  • Patent number: 12328180
    Abstract: The present disclosure provides a method for predicting co-channel interference (CCI) of a satellite-to-ground downlink under a low-orbit satellite constellation. The method includes: obtaining CCI values in a first time period and CCI values in a second time period; constructing a CCI model based on the CCI values in the first time period and a dropout wavelet neural network (WNN); updating parameters of the CCI model; inputting the CCI values in the second time period into an updated CCI model to obtain accuracy; determining whether the accuracy is greater than an accuracy threshold; and if the accuracy is greater than the accuracy threshold, reconstructing the CCI model; or if the accuracy is less than or equal to the accuracy threshold, outputting the updated CCI model; and predicting CCI values of each link at a next moment based on the updated CCI model.

  • Publication number: 20250067657
    Abstract: The disclosed flow cytometer includes a wavelength division multiplexer (WDM). The WDM includes an extended light source providing light that forms an object, a collimating optical element that captures light from the extended light source and projects a magnified image of the object as a first light beam, and a first focusing optical element configured to focus the first light beam to a size smaller than the object of the extended light source to a first semiconductor detector. The disclosed flow cytometer further includes a composite microscope objective to direct light emitted by a particle in a flow channel in a viewing zone of the composite microscope to the extended light source, a fluidic system and a peristaltic pump configured to supply liquid sheath and liquid sample to the flow channel, and a laser diode system to illuminate the particle in the flow channel.
