Abstract:
This paper is concerned with the analysis
of exact symbol error probability (SEP) for
cooperative diversity using amplify-and-forward
(AF) relaying over independent and non-identical
Nakagami-m fading channels. The mathematical
formulations for Probability Density Function (pdf)
and Moment Generating Function (MGF) of a
cooperative link have been derived for calculating
symbol error probability with well-known MGF
based approach taking M-ary Phase Shift Keying
(MPSK) signals as input. The numerical results
obtained from this research have been compared
with different fading conditions. It is observed that
the existence of the diversity link in a relay network
plays a dominating role in error performance.
