Power Allocation for Multi-Satellite System Integrated with Precoding and User Scheduling

摘要

The urgent demand for high throughput satellites providing broadband interactive service drives the research for new architectures of Satellite Communication(SatCom)^{systemsand the multi-satellite system becomes more concerned. Meanwhile, full frequency reuse techniques and the exploitation of spatial resources are still crucial for the multi-satellite system. To improve the capacity of the multi-satellite system further, in this paper, we propose an SCA based power allocation scheme for coordinated mutiple multibeam satellite systems, where the cutting-edged techniques including user selection and precoding are considered. Simulations show that our method could improve the capacity of the system on the basis of the user selection and outperforms the classical IWF method while the integrated performance of the system is also investigated.}
