BER Simulation for Dual Hop Relaying System over Various Fading Channelsunder Different Condition

This paper shows the study of Bit Error Rate (BER) using differential dual hop relaying system over Alpha-mu fading channel, Generalized- Gamma fading channeland Rician fading channel between Source to Relay/Relay to Destination i.e. (S-R)/(R-D). Here, two modulation techniques; DQPSK and DBPSK are used along with three channel schemes; SR - Slow Fading and RD - Slow Fading, SR- Fast Fading and RD- Slow Fading and SR - Fast Fading and RD - Fast Fading for the analysis of BER. Firstly, the BER is simulated over the combination of Alpha-mu fading channel andRician fading channel. Also, similar analysis has been achieved over the combination of Generalized Gamma fading channel and Rician fading channel. Finally, the results have been verified through the numerical analysis.
