基于卫星通信多模切换的射频资源池FPGA虚拟化技术研究
Research on FPGA virtualization of RF resource pool for multi-mode bearer technology in satellite communications
摘要
Abstract
With the continuous surge in global communication demands,satellite networks are experiencing unprecedent-ed rapid development,characterized by the fusion and coexistence of multiple heterogeneous systems.This trend poses unprecedented challenges to the multi-mode switching capabilities of satellite ground gateways.To address this issue,this paper proposes a virtualization technology based on the radio frequency resource pool,which aims to enable the loading of multi-user and multi-mode algorithms under limited hardware resources while meeting the stringent requirements of the system for multi-mode switching delay.By adopting a compilation method that com-bines static and dynamic compilation,local dynamic configuration on the field-programmable gate array(FPGA)is achieved,facilitating rapid switching between multiple operations to support instant conversion of multi-mode wave-forms.Simulation results demonstrate that the combined static-dynamic compilation method can save 50%of FPGA logic resources.Moreover,the average time for parameter reconfiguration is 40 μs,which is merely one ten-thou-sandth of the average 420 ms required for static configuration,thereby proving the feasibility and practicality of this technology.关键词
