Embodiment 1
[0109] The diversity access method based on iterative detection in the UAV cluster measurement and control of the present invention is analyzed.
[0110] Such as figure 1 Shown is a schematic diagram of the time-frequency planning of the diversity access method based on iterative detection in the UAV cluster measurement and control of the present invention. For example, the superframe can be designed to contain 10 frames, and there are 6 frequency points in total. The superframe length is 200ms, and the frame length is 20ms. The point bandwidth is 1MHz, the frequency band guard interval is 0.2MHz, the frame contains 40 long time slots of 0.5ms, the guard interval in the time slot is 0.1ms, the length of the preamble segment is 208, the length of the signaling segment is 192, and the effective information of the signaling segment is 128 bits. QPSK modulation, 1 / 3 code efficiency Turbo code, 60 first time slots for random access and control, the first frequency point corresponds...
