Study of an UWB Communication Channel in the MAV
Aim at the lower height transmission environment by using the ultra wide band wireless signal in the communication link of micro air vehicle,analyse the probable existing landform and area in the propagation channel,and its impact on the pathloss of UWB signal.Select the modified S-V multipath channel model,simulate two choosed propagation environments,give the results including pathloss,impulse response,rms delay spread,mean excess delay,number of multipath components and power delay profile.The results indicate that this model can reflect the channel characteristic parameters efficiently,it can be used as reference of the design of UWB receiver.
