  • Sweep voltage generator and display panel
    Patent number: 11967272
    Abstract: A sweep voltage generator and a display panel are provided. The sweep voltage generator includes an output node, a current generating block and a voltage regulating block. The output node is used to provide a sweep signal. The current generating block is coupled to the output node, includes a detection path for detecting an output load variation on the output node, and adjusts the sweep signal provided by the output node based on the output load variation. The voltage regulating block is coupled to the output node for regulating a voltage of the output node.

  • User selection method for non-orthogonal multiple access system and base station thereof
    Patent number: 10925063
    Abstract: The disclosure provides a user selection method for non-orthogonal multiple access (NOMA) systems and a base station thereof. The method includes: (1) initializing the cluster-partition parameter i to be 2; (2) dividing N user devices into i clusters; (3) selecting a reference device from each of the i clusters to form a reference cluster; (4) performing a power allocation algorithm for the reference cluster to calculate a power allocation factor for each of the reference devices; (5) determining whether each of the reference devices with the calculated power allocation factors meets a set of constraints: if all of the reference devices meet the set of constraints, increasing the value of i by 1 and then going back to step (2); if any one of the reference devices does not meet the set of constraints and i is not equal to 2, performing NOMA transmission for the reference cluster.
