摘　　要：由于毫米波频段的可用频谱资源相对较窄,频谱拥挤会导致无人机(UAV)通信中断,且信道带宽估值过大或过小都不利于无人机毫米波通信的实施。为了顺利实施无人机毫米波通信,提出无人机毫米波通信信道带宽估计方法。在无人机控制器中设置可编程门阵列(FPGA)缓存模块,根据通信容量使用混合编帧处理毫米波通信数据。选择动态通信节点,根据数据覆盖率设计无人机通信编码方案。利用通信导频插入条件,获取自适应通信阶数,定义正则化估计参数,实现对信道带宽的估计。测试结果表明,所提方法下的毫米波通信更加稳定,且带宽数值保持在5×10^(11)Mibit以下,信道带宽估值与真实信道带宽占用量之间的差值始终未超过1.0×10^(11)Mibit,有利于保障无人机毫米波通信的顺利实施。Due to the relatively narrow available spectrum resource in the millimeter wave band,spectrum congestion will lead to the interruption of unmanned aerial vehicle(UAV)communication,and too large or too small channel bandwidth estimation is not conducive to the implementation of UAV millimeter wave communication.In order to implement the millimeter wave communication of UAV smoothly,a method of the bandwidth estimation of UAV millimeter wave communication channel is proposed.The field programmable gate array(FPGA)cache module is set in the UAV controller to process the millimenter wave communication data by mixed coding frame according to the communication capacity.Select the dynamic communication node and design the UAV communication coding scheme according to the data coverage.The adaptive communication order is obtained by the communication pilot insertion condition,and the regularization estimation parameters are defined to realize the estimation of the channel bandwidth.The test results show that the millimeter wave communication is more stable under the proposed method,and the bandwidth value is always below 5×1011 Mibit,and the difference between the estimated channel bandwidth and the real channel bandwidth usage does not exceed 1.0×1011 Mibit,which is conducive to the smooth implementation of millimeter wave communication for UAV.
