Nonlinearities impact on RPAS data transmission

Model of remotely piloted aircraft systems orthogonal frequency division multiplexing communication channel “RPAS-Ground Station” with adaptive modulation was built on a basis of IEEE 802.16 standard. The model with adaptive modulation consists of a source of information, remotely piloted aircraft systems transmitter, downlink path, and ground station receiver. Parameters of a channel with transmitter nonlinearities were obtained and analyzed.
