Interference Mitigation Techniques For The Operation Of Unmanned Aerial Vehicle (Uav)

The unmanned aerial vehicles (UAVs) have turned to the emerging topic in both industry and academia era. Package delivery, agriculture, surveillance, search and rescue are now combined with the UAV connectivity that promise to change the current lifestyle. As such, the mitigation techniques have significant impact on the performance of the UAVs. To tackle the interference issue, this paper presents the in-depth investigation on the interference caused by the unmanned aerial vehicle (UAV) to the existing Long-Term Evolution (LTE) network. The total of three different mitigation techniques are investigated and the qualitative comparison between the techniques resulted from the simulation by SEAMCAT software, is presented accordingly. In particular, the obtained results from beamforming and CoMP techniques in LOS and NLOS conditions show the interference reduction of 13 to 15 dBm in LOS condition.
