“…Identically distributed fading links are assumed in this example such that K 1 = K 2 = K, m 1 = m 2 = m and γ 1 = γ 2 = γ. Note that the outage probabilities for Rician systems are directly obtained using (15), while those for Nakagami-m systems are obtained using [9, eq. (2)].…”

“…In [14], the authors also studied the case of mixed Rayleigh/Rician fading channels for fixed-gain dual-hop AF relaying systems, and obtained infinite-series representations for the outage probability and the average bit error probability of these systems. In [15], the performance of dual-hop AF systems operating over Nakagami-m/Rician fading links was evaluated for variable-gain relaying. However, such performance was not evaluated for the case when both links are Rician faded.…”

A unified performance analysis is presented for dualhop amplify-and-forward (AF) relaying systems operating over non-identically distributed Rician fading channels. A general, two-parameter AF relaying model is used to cover various AF relaying schemes, namely, variable-gain AF relaying, fixedgain AF relaying, and channel-assisted relaying, as well other unconventional schemes. Although, in some applications, systems operating over Rician fading links can be approximated and analyzed using equivalent systems operating over Nakagami-m fading links, we show that this is not sufficiently accurate in the case of AF relaying systems. Therefore, single-fold infiniteseries expressions for the probability density function (PDF) and the cumulative distribution function (CDF) of the instantaneous end-to-end received signal-to-noise ratio (SNR) of such systems are derived, and Monte-Carlo simulations are used to verify the precision of the derived expressions. In addition, the effects of the relaying model parameters, as well as the channel fading parameters, on system performance are studied.Index Terms-Amplify-and-forward, average symbol error probability, cooperative systems, dual-hop relaying, outage probability, Rician fading.

“…In these works, they derived a cumulative distribution function (CDF) to analyse the system performance. In [4,5], the authors proposed exact expressions for two-hop AF relaying systems over Nakagami-m/Rician fading channels as well as Rician/Rician and Nakagami-m/Nakagami-m fading channels. Kapucu et al [6,7] investigated the performance of two-hop regenerative relaying systems under mixed Rayleigh/Gamma and Rayleigh/Weibull fading conditions.…”

This paper presents analytical solutions for the performance of a single relay aided amplify-and-forward (AF) direct sequence code division multiple access (DS-CDMA) system over Rayleigh/Nakagami-m fading channels. The source-destination channel is assumed to be Rayleigh distributed while relay-destination link is Nakagami-m distributed. First, a cumulative distribution function (CDF) is derived for the source-relay-destination link and the derived CDF expression is used to evaluate the outage probability. Then, a moment generating function (MGF) is obtained through integral evaluation of the derived CDF expression in order to evaluate the average error probability of the considered system. Finally, the accuracy of the proposed analytical expressions are confirmed by computer simulations.
