Patent number: 11831393Abstract: 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.Type: GrantFiled: October 10, 2019Date of Patent: November 28, 2023Assignee: SOUTHEAST UNIVERSITYInventors: Xiqi Gao, Li You, Kexin Li, Jiaheng Wang, Wenjin Wang

Publication number: 20230327752Abstract: The present invention discloses a satellite-based blockchain architecture, including a terrestrial blockchain miner network, a constellation system, and a consensus protocol coordinating the constellation system and the terrestrial blockchain miner network. In each round, a satellite generates an oracle, and satellites broadcast the oracle to the terrestrial blockchain miner network. The oracle selects a terrestrial miner as a winner of the current round based on a specific rule. The winning terrestrial miner has the right to generate a new block in the round, and broadcasts the new block to other miners by using the terrestrial blockchain miner network. Other miners receiving the new block check the validity of the block, and if the check succeeds, the block is broadcast to other miners by using the terrestrial blockchain miner network.Type: ApplicationFiled: September 22, 2021Publication date: October 12, 2023Inventors: Xintong LING, Pengcheng CHEN, Zheng GAO, Yuwei LE, Jiaheng WANG, Li YOU, Xiqi GAO
