【Abstract】 In this paper,we analyze the channel characteristic of the telecontrol telemetry and information transmission system of UAV,and propose the different channel models by a series of flight status and environment.Based on the channel models,we design the relevant channel emluators that can emulate different communication channels by setting some parameters.The channel emluators can be used for the validation of the receiver performance of the telecontrol telemetry and information transmission system of UAV.更多还原
