Abstract: A channel state information CSI compression and feedback solution based on deep learning. In a large-scale multiple-input-multiple-output MIMO system, CSI is very important for the base station to achieve high performance gain. In a frequency division duplex FDD mode, user equipment UE needs to estimate CSI and then feed it back to the base station. Effective CSI compression will greatly reduce the cost of feedback. The present disclosure uses a two-dimensional sequence-to-sequence 2D Seq2Seq structure neural network to realize effective CSI compression and reconstruction. The base station uses CSI data to train the parameters of the neural network, which, after training, are deployed at the client and the base station for effective CSI compression and reconstruction. The present disclosure can realize high-precision compression and reconstruction of CSI, and provides an efficient and stable channel state information feedback method for a MIMO system.

Abstract: The present invention discloses a method and a device for laser-assisted electrochemical composite deposition using a rifling-type hollow rotating electrode, which relate to the field of micro-composite processing in special processing technologies. A center of a laser beam is allowed to pass through a rifling-type hollow rotating electrode and focus onto a cathode substrate. When the rifling-type hollow rotating electrode is rotated at a constant speed, an electrodeposition solution rotates in the rifling-type hollow rotating electrode and generates a certain centripetal force to improve the precision and localization of deposition. During the process of the present invention, an internal rifling structure of the electrode is rotated at a high speed so that the deposition solution generates a centripetal force. The internal rifling structure and an external helical structure of the rifling-type hollow rotating electrode make the deposition solution move upward to form a “self-circulation” system.

Abstract: Disclosed are a device and a method for microelectrodeposition through a laser assisted flexible following tool electrode. Localization of electrodeposition and dimensional precision of members are enhanced by using the flexible following tool electrode to restrict a dispersion region of an electric field and a reaction region of electrodeposition, and a complex-shaped member can be deposited by controlling a motion path of the flexible following tool electrode. Since a laser has a high power density, introducing laser irradiation changes an electrode state in a radiated region, accelerates ion diffusion and electron transfer speeds, and increases a deposition rate, thus reducing defects such as pitting and cracking in a deposit, enhancing deposition quality, and achieving fabrication of a micro-part by a synergistic action of both electrochemical energy and laser energy.
