Abstract
An approach to the performance analysis of dual hop amplify-and-forward relay transmission system, in the asymmetrical fading environment is presented. The main contributions of this paper are closed form expressions for the exact and lower bounds of important performance measure, an outage probability. In order to show the effects of system parameters on overall performance numerically obtained results are graphically presented. Also graphical analysis is provided for another performance measure, an average bit error probability.

Highlights
Wireless systems in the future will be envisaged to offer ubiquotious high data-rate coverage in large areas
Several studies have shown that the Hoyt fading model provides a very accurate fit to experimental channel measurements in a various communication applications, like mobile satellite propagation channels and spans the range of the fading figure from the one-sided Gaussian to the Rayleigh distribution
The Hoyt distribution can be considered as an accurate fading model for satellite links with strong ionospheric scintillation
Summary
Wireless systems in the future will be envisaged to offer ubiquotious high data-rate coverage in large areas. In [2] lower bounds for the performance of a two hop channel state information (CSI) assisted AF relay system over non identically distributed generalized gamma fading channels have been presented. [3] studies the ABEP of two hop systems with AF relaying over Rayleigh fading channels. The main contributions of this paper are outage probability closed form expressions for the exact and lower bounds which become tight for high signal-to-noise ratios (SNRs). Numerical results are graphically presented in order to discuss the effects of fading parameters on overall system performance Another important performance measure, an average bit error probability over different modulation schemes is analyzed. Another useful measure for evaluating the performance of wireless communication applications is the average bit error probability (ABEP). For various values of γth and Hoyt fading severity parametar q is presented at Fig. 1 and Fig
