基于非专用中继节点的双跳中继用频规划

Spectrum Planning of Dual-Hop Relay Based on Non-Exclusive Relay Nodes

联合战术通信背景下,一级通信节点和所属的某些二级通信节点之间由于通信距离过大或地理阻隔,传统的以一级通信节点为中心的单跳超短波组网已无法满足通信需求。从具体的战术通信实际出发,针对不同层次的战术通信网提出了一种超短波频段的频率划分及复用方案,设计了以二级通信节点为中继的用频规划方案,实现了一级通信节点和另一二级通信节点之间的双跳中继通信,有效拓展了一级节点的通信范围。仿真验证了所提的中继用频规划方案的有效性。

In joint tactical communications,due to the deterioration of channel resulting from the communication distance and obstruction,the primary communication node may lose contact with some suborilinated secondary communication nodes under single-hop protocol in VHF frequency band.Motivated by it,in this paper,we proposed a division and reuse scheme in VHF frequency band aiming at different level tactical communication networks.Further,based on this scheme,we put forward a relay frequency planning at the secondary node and realized the dual-hop relay communication between the primary node and another secondary node.The communication range of the primary node has been greatly extended with the limited spectrum resource.The validity of the relay frequency planning was verified through simulations.
