However, the dynamic characteristics brought by low Earth orbit (LEO) satellites will seriously decrease the data rate and make the data rate fluctuate. In this paper, dual-stream transmission and downlink power control for multiple LEO satellites-assisted IoT networks are investigated. To mitigate the effects of the frequency offset caused by different LEO satellites, a multi-satellites synchronization scheme is proposed. Then, different power control schemes are given to resist the data rate fluctuation during the transmission. The simulation results show that the proposed schemes can effectively compensate for the varied frequency offset and keep the data rate stable.<\/jats:p>","DOI":"10.3390\/s22166050","type":"journal-article","created":{"date-parts":[[2022,8,15]],"date-time":"2022-08-15T23:44:03Z","timestamp":1660607043000},"page":"6050","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Dual Stream Transmission and Downlink Power Control for Multiple LEO Satellites-Assisted IoT Networks"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7648-4695","authenticated-orcid":false,"given":"Bingyu","family":"Xu","sequence":"first","affiliation":[{"name":"China Academy of Information and Communications Technology, Beijing 100191, China"},{"name":"Innovation Center for Satellite Communication System, China National Space Administration, Beijing 100191, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiayu","family":"Li","sequence":"additional","affiliation":[{"name":"China Academy of Information and Communications Technology, Beijing 100191, China"},{"name":"Innovation Center for Satellite Communication System, China National Space Administration, Beijing 100191, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yujuan","family":"Ma","sequence":"additional","affiliation":[{"name":"China Academy of Information and Communications Technology, Beijing 100191, China"},{"name":"Innovation Center for Satellite Communication System, China National Space Administration, Beijing 100191, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xing","family":"Xin","sequence":"additional","affiliation":[{"name":"School of Electronic Engineering, Beijing University of Posts and Telecommunications, Beijing 100876, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michel","family":"Kadoch","sequence":"additional","affiliation":[{"name":"Ecole de Technologie Sup\u00e9rieure, Montreal, QC H3C 1K3, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,8,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"150","DOI":"10.1109\/MNET.001.2100148","article-title":"Key Technologies in 6G SAGS IoT: Shape-Adaptive Antenna and Radar-Communication Integration","volume":"35","author":"Hong","year":"2021","journal-title":"IEEE Netw."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1007\/s11432-020-2955-6","article-title":"Towards 6G wireless communication networks: Vision, enabling technologies, and new paradigm shifts","volume":"64","author":"You","year":"2021","journal-title":"Sci.
