  • Publication number: 20230261905
    Abstract: A user equipment, a base station, a joint training device for a user equipment and a base station, a joint channel estimation and feedback system for a user equipment and a base station, a feedback channel state information generation method, a channel matrix generation method, a joint training method, and a joint channel estimation and feedback method for a user equipment and a base station in wireless communication. Feedback channel state information is generated by a user equipment according to an actual pilot signal, and a deeper residual learning neural network is introduced into a base station to reconstruct a channel matrix of the base station according to the feedback channel state information. As such, it is possible that the base station can reconstruct a complete high-resolution channel matrix even if an actually received pilot signal is an incomplete low-resolution part.

  • Publication number: 20230182209
    Abstract: An ultra-high speed laser cladding device and a process based on the dual suppression of magnetic force and centrifugal force are provided, including a laser generator, a spectrometer, a powder device, a rotary tool and a magnetic field generator. The substrate is installed in the rotary tooling, through the driving device to rotate it. The magnetic field generator is used to generate a magnetic field in the rotary cylinder. The laser generator produces the first laser beam and the second laser beam with different energy through the spectrometer. They are both focused on the surface of the substrate. The powder conveyed by the powder device is sprayed to the surface of the substrate, laser cladded by the first laser beam and the second laser beam. The gas can quickly escape to ensure the density of the cladding layer and reduce the porosity.
