摘要
无人机组在协同通信中使用双路移动中继实现无人机与地面基站通信系统的连接、数据和信息同步。若双路移动中继之间的干扰没有抑制,信息源和中继的同步数据传输性能会明显下降。为了抑制双路移动中继之间的干扰,提出全干扰对消的方法。理论分析和实验测试结果证实了全干扰对消方法相对部分干扰对消方法对干扰抑制更有效,更适合移动终端的低计算复杂度需求。
Two-way mobile relays are employed for UAV( Unmanned Aerial Vehicle) to achieve the connection,data and information synchronization of the communication system between the UAV and the ground base station in the cooperative communication. If the interference between the two path relays is not suppressed,the performance of synchronous data transmission from the information source and the relay will be significantly decreased. In order to suppress the interference between two path relays,this paper presents a method of full interference cancellation.Theoretical analysis and experimental results demonstrate that,in comparison with the partial interference cancellation algorithm,the full interference cancellation algorithm is more effective for interference suppression and more suitable for the low computational complexity of mobile terminals.
