Abstract

First built models of Remotely Piloted Air System (RPAS) communication channels based on Wideband Code Division Multiple Access (WCDMA) 3GPP Standard were designed. Base Station (BS) transmission within the Radio Line of Sight (RLoS) and through the satellite using Beyond Radio Line of Sight (BRLoS) was considered. The dependencies of the Bit Error Rate (BER) on the signal-noise ratio for different RPAS velocities and WCDMA сhannel models were obtained. The dependences of the BER on the signal-noise ratio for different levels of satellite transponder nonlinearity were studied. The dependence of the BER on the BS antenna diameter in case of the transponder nonlinearity was analysed. The dependencies for satellite channel characteristics, first obtained taking into account the motion of the RPAS, make it possible to predict the behavior of the communication system in critical conditions.

Highlights

Advances in technology of the Remotely Piloted Air System (RPAS) or the Unmanned Aerial Vehicle (UAV) led to the creation of RPASs with various sizes, which have on board enhanced processing, memory, data storage and communication capabilities
The tasks of this of this research work: 1) to build models of RPAS communication channels based on Wideband Code Division Multiple Access (WCDMA) 3GPP Standard, including both Base Station (BS) transmission within the Radio Line of Sight (RLoS), and through the satellite using Beyond Radio Line of Sight (BRLoS) using MATLAB software; 2) to obtain the dependencies of the Bit Error Rate (BER) on the signal-noise rate for different RPAS velocities and WCDMA RLoS channel models; 3) to obtain the dependencies of the BER on the signal-noise ratio for different levels of satellite transponder nonlinearity; 4) to study the dependence of the BER on the BS antenna diameters in case of the transponder nonlinearity
RPAS applications are very promising and useful, but many technical and organizational challenges have to be addressed in order to exploit drones successfully

Summary

Introduction

Advances in technology of the Remotely Piloted Air System (RPAS) or the Unmanned Aerial Vehicle (UAV) led to the creation of RPASs with various sizes, which have on board enhanced processing, memory, data storage and communication capabilities. Among the emerging research areas and potential applications, the most attractive are UAVs use in the fifth generation wireless networks, due to benefits in terms of improved coverage, less implementation costs, less latency and more reliability. There are no characteristics of the satellite channel, which allow predicting the behavior of the communication system in critical conditions The tasks of this of this research work: 1) to build models of RPAS communication channels based on WCDMA 3GPP Standard, including both BS transmission within the RLoS, and through the satellite using BRLoS using MATLAB software; 2) to obtain the dependencies of the Bit Error Rate (BER) on the signal-noise rate for different RPAS velocities and WCDMA RLoS channel models; 3) to obtain the dependencies of the BER on the signal-noise ratio for different levels of satellite transponder nonlinearity; 4) to study the dependence of the BER on the BS antenna diameters in case of the transponder nonlinearity
