Abstract: The present disclosure discloses a preparation method of ginseng composition with high ginsenoside bioavailability. The composition is composed of ginseng powder of 250 meshes or more and ?-cyclodextrin, and the mass ratio of the ginseng powder to the ?-cyclodextrin is 1:0.05. Results show that when ?-cyclodextrin is used as a solid dispersant and added to the 1000-mesh ginseng powder at a mass ratio of 5%, the total dissolution amount is maximum; and furthermore, animal experiments (SD rats) show that the area under the plasma drug concentration-time curve (AUC0-48 h) after 48 h of ginseng powder ingestion is maximum, indicating that in-vivo bioavailability of the ginseng powder is the highest. The method of this application can effectively inhibit the aggregation of the ultra-finely pulverized 1000-mesh ginseng powder by adding the ?-cyclodextrin, thus significantly improving the total dissolution amount of ginsenoside.

Abstract: The present invention discloses a large-scale MIMO satellite mobile communication method and system. A satellite or gateway station uses spatial angle information of user terminals to group the users to be served in the coverage area to form space division user groups, wherein the user terminals in the same group use the same time-frequency resources to communicate with the satellite, while the user terminals in different groups use different time-frequency resources to communicate with the satellite. For the user terminals in the same space division user group, the satellite or gateway station uses statistical channel information of each user terminal to calculate a downlink precoding vector and an uplink receiving processing vector corresponding to each user terminal, and then uses the obtained vectors to perform downlink precoding transmission and uplink received signal processing.
