Abstract
The article considers possible variants of application of various MIMO schemes for the communication with the drone or unmanned aerial vehicle. The model of multipath propagation of radio waves taking into account polarization parameters of antennas is given. The main focus is on the use of MIMO technology with polarization-orthogonal channels and channels with double polarization. The evaluation of the efficiency of using full polarization reception in comparison with MIMO channels of one polarization is given. Attention is paid to the presence of cross-polarization solution between the channels.
Highlights
The requirements for communication channels with drones have gradually evolved from ensuring the continuity and reliability of the control channel to a communication channel that requires large amounts of data
This power normalization process is based on the following assumptions: for a MIMO system with transmit antennas M and receiving antennas N total channel power is K=MN
Thanks to the use of full polarization reception due to antennas of dual orthogonal polarization, it turned out to be possible to improve the average value of the specific capacity of the communication channel with the drone and reduce the value of spatial correlation at the zero level, which is important in the design of promising communication channels and the design of antennas
Summary
Increasing the throughput of the communication channel with the drone is possible due to the use of multi-polarized antennas on the transceivers. The technology of using MIMO antennas of dual polarization will allow full polarization reception of signals, which will reduce losses during propagation of radio waves in multipath conditions, can solve the problem of insufficient bandwidth, and increase the reliability of the communication system as a whole. The use of MIMO technology with polarization-orthogonal channels has become a promising research area for next-generation mobile and fixed communication systems [1–3]. The aim of the article is study of the possibility of increasing the capacity of the communication channel with an unmanned aerial vehicle using MIMO antennas with polarized orthogonal antennas
