PERFORMANCE OF DUAL-HOP RELAYING OVER SHADOWED RICEAN FADING CHANNELS

Aleksandra M. Cvetković – Jelena Anastasov – Stefan Panić – Mihajlo Stefanović – Dejan Milić

   In this paper, an analytical approach for evaluating performance of dual-hop cooperative link over shadowed Ricean fading channels is presented. New lower bound expressions for the probability density function (PDF), cumulative distribution function (CDF) and average bit error probability (ABEP) for system with channel state information (CSI) relay are derived. Some numerical results are presented to show behavior of performance gain for the proposed system. Analytical exact and lower bound expression for the outage probability (OP) of CSI assisted relay are obtained and required numerical results are compared.

Keywords: dual hop cooperative system, CSI relay, shadowed Ricen fading
