ASER Analysis of a DF Relay-Assisted Transmission System Influenced by Fisher-Snedecor F Fading Channels Applying Non-coherent Modulation Schemes

The effect of shadowing and multipath fading goes hand in hand in wireless communication systems. In this paper, a study on a composite type of fading channel is performed. The ASER analysis is carried out deploying the Fisher-Snedecor F fading channel considering the DF-type relay in the transmission system wherein a direct link is also considered between the source and the receiver. Mathematical statements of PDF, CDF, and OP are hence derived. MGF expression is shown in respect of Meijer’s G function, which is then used to procure the ASER of the system. At the receiver end MRC technique combines the SNR of the signals received. Non-coherent modulation schemes like NCBFSK and DBPSK are used for the analysis purpose of the ASER. The results show that ASER performs better at high values of SNR, which is the desired result. Similarly, DBPSK modulation is seen to give an improved performance of ASER than NCBFSK. Simulation is carried out to verify the ASER statements.
