Abstract
Performance of dual-hop amplify-and-forward relaying system is analyzed over asymmetrical Nakagami-m/Rcian and symmetrical Nakagami-m/Nakagami-m fading channel with space shift keying (SSK) modulation. Expressions for average bit error probability (ABEP) of SSK modulation scheme over the line-of-sight and non-line of sight fading channels have been obtained. Analytical expressions for cumulative distribution function of the end-to-end signal-to-noise ratio are derived and a mathematical expression for the ABEP of SSK modulation is obtained for both in presence of the direct link between source to destination and in absence of the direct link. The derived expressions are given in terms of the Whittaker functions and Gamma functions. ABEP expressions are also derived which provide useful insights into the factors governing the performance of the considered system. The numerical results have been verified with Monte-Carlo simulation results.
