Abstract: The general communication system is a single-input and single-output (SISO) system, which is very simple to implement. The average symbol error rate (ASER) applying various quadrature amplitude modulation (QAM) techniques is analysed to observe the functioning of the SISO system. QAM schemes are more useful to increase bandwidth efficiency concerning fifth-generation (5G) and beyond wireless transmission systems. The channel of the system is influenced by Fisher-Snedecor F composite distribution. This distribution is commonly applied to represent fading channels due to its high accuracy and mathematical conformity. Various QAM schemes like hexagonal QAM, cross-QAM, square QAM as well as rectangular QAM are employed for ASER derivations. ASER expressions are acquired with regard to the Fox H-function which is the most general function, and Prony approximation for Gaussian Q-function is utilised. Computer simulation is achieved to verify the certainty of the analysed ASER equations.

Keywords: Fisher-Snedecor F fading; ASER; average symbol error rate; QAM; quadrature amplitude modulation; Prony approximation.
