RT Journal Article T1 On the ASER performance of UAV-based communication systems for QAM schemes A1 Dixit, Dharmendra A1 Kumar, Nagendra A1 Sharma, Sanjeev A1 Bhatia, Vimal A1 Panic, Stefan A1 Stefanovic, Caslav AB In this letter, we derive an average symbol error rate (ASER) expression of rectangular quadrature amplitude modulation (RQAM) scheme for unmanned aerial vehicle-enabled communication systems operating over double-shadowing and double-scattering composite fading channel. A moment generating function for the receiver output signal-to-noise ratio is obtained to analyze the ASER expression of non-coherent modulation schemes. An asymptotic expression of ASER for RQAM scheme is also derived to examine diversity order of the considered system. Further, the impact of composite fading parameters and path loss on ASER performance is highlighted. Finally, we validate all the theoretical results through Monte Carlo simulations.
