Research on Bandwidth Estimation of Unmanned Aerial Vehicle Millimeter Wave Communication Channel
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 com-munication of UAV smoothly,a method of the bandwidth estimation of UAV millimeter wave communication channel is pro-posed.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 ob-tained by the communication pilot insertion condition,and the regularization estimation parameters are defined to realize the es-timation of the channel bandwidth.The test results show that the millimeter wave communication is more stable under the pro-posed method,and the bandwidth value is always below 5×1011 Mibit,and the difference between the estimated channel band-width 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.
