BER analysis of various modulation schemes over GG fading channel for differential dual hop relaying system

Differential dual hop relay based system has been introduced to solve the coverage problem. However, fading channel is the weak link of any wireless system. Generalized Gamma (GG) distribution is one of the fading models of wireless communication. However, GG fading channel is not available in any of the software packages. This research paper presents BER analysis of differential dual hop relaying system followed by simulating GG fading channel. Different modulation schemes namely DBPSK and DQPSK have been considered for analyzing the BER of the above system. Furthermore, different channel scenarios between source-relay (SR) and relay-destination (RD) also have been considered for analyzing the above system. Namely, when both SR & RD is slow fading, when SR is fast fading & RD is slow fading and when both SR & RD is fast fading. Numerical analysis also shows the validity of results.
