  • Patent number: 11238255
    Abstract: The security of a QR code is substantially increased by removing an alignment pattern and/or a position detection pattern from a complete QR code to form an incomplete QR code. A complete QR code can be regenerated from the incomplete QR code with the proper imaging angle to the incomplete QR code. A malicious operator is unlikely to be able to obtain the proper imaging angle and is thereby unable to reconstruct a complete QR code from the incomplete QR code.

  • Publication number: 20210288715
    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.
