摘　　要：多波束卫星广泛采用三色/四色等传统频率复用方案,建立了多波束卫星系统模型,并将地面移动通信中的同频组网技术引入多波束卫星通信系统中,提出了一种基于带宽协调的频率复用技术。该技术将系统资源分配分为波束间资源分配和波束内资源分配,波束间资源基于部分频率复用方法进行分配,波束内资源采用均匀方式和基于注水算法2种方式进行分配。仿真结果表明,相比于传统复用技术,所提出的基于带宽协调的频率复用技术在系统总吞吐量性能方面有较大提升。Three-color,four-color and other traditional frequency multiplexing schemes are widely used by multi-beam satellites.A multi-beam satellite system model is established,and the same frequency networking technology in ground mobile communication is introduced into multi-beam satellite communication system.A frequency multiplexing technology based on bandwidth coordination is proposed,in which the system resource allocation is divided into resource allocation among beams and resource allocation within the beam.The resource allocation among beams is based on partial frequency multiplexing technology,and the resource allocation within the beam is based on even distribution and water injection algorithm.Simulation results show that compared with the traditional multiplexing technology,the proposed frequency multiplexing technology based on bandwidth coordination has greatly improved the total throughput performance of the system.
