  • Patent number: 12191940
    Abstract: A user matching and power distribution methods for a MIMO-NOMA downlink communication system is provided. The user matching method includes: dividing all users into a strong user group and a weak user group according to a channel gain sorting result; and sequentially selecting a user in the strong user group, calculating a correlation coefficient between the user and each user in the weak user group, selecting a weak user with the highest correlation coefficient as a weak user in a cluster where the strong user is located, and excluding matched users from respective user groups, until the matching between all strong users and weak users are completed. The present invention enables weak users in a cluster to experience less inter-cluster interference in scenarios where the channel correlation between users is relatively low, thereby improving the total throughput of the communication system.

  • Patent number: 11993541
    Abstract: The present invention discloses a multitype-adsorptive-group polycarboxylic acid water-reducing agent, consisting of 30-60 wt % of a macromolecule with multitype-adsorptive groups and water, the macromolecule with multitype-adsorptive groups has a polyethylene glycol side chain, and adsorption groups of the polymer backbone include a carboxylic acid group, a sulfonic acid group and a phosphoric acid group, the phosphoric acid group being linked to the backbone of the macromolecule with multitype-adsorptive groups by nucleophilic addition. The water-reducing agent of the present invention has significantly improved adaptability to different cements and aggregates while maintaining a high water reduction efficiency, compared with the conventional polycarboxylic acid water-reducing agent agent. It has a good water reducing efficiency in many different grades of cement, as well as a better resistance to aggregates containing more impurities such as machine-made sand.

  • Patent number: 7370644
    Abstract: An ECU calculates a foreign-matter accumulation index base on a total flow rate of EGR gas integrated since the previous execution of a last foreign-matter removal operation until the present execution of the foreign-matter removal operation. The ECU controls an actuator for operating an EGR valve and a number of the actuations of the EGR valve on the basis of the foreign-matter accumulation index. When the total flow rate of the EGR gas increases, the quantity of foreign matters contained in EGR gas correspondingly increases. Therefore, as the foreign-matter accumulation index becomes larger, the actuation intensity of the EGR valve is set higher and the number of the actuations of the EGR valve is set larger. As a result, the removal operation of foreign matters can be efficiently executed in accordance with the deposition intensity or the deposition quantity of foreign matters.
