RETRACTED ARTICLE: Performance of single hop and multi hop relaying protocols in cognitive radio networks over Weibull fading channel

Abstract

With the rapid growth of wireless communication, there is an extensive growth in the demand of Radio frequency through electromagnetic spectrum allocation. Cognitive radio is considered to be a potential technology which helps to overcome the demand in radio frequency. Relaying protocol is applied in this paper in order to assist the transmission, improve the efficacy and to minimize the bit error rate. The performance of single hop (Amplify and Forward-AF) and multi-hop (Decode and Forward-DAF and Compress and Forward-CF) relaying protocols over a Weibull fading channels in cognitive radio are analyzed. The numerical outcomes are evidence that the bit error rate and Signal to Noise ratio proves that multi-hop is more promising as compared to single-hop relaying protocol.
