| contents | Effect of Primary Interference on Cognitive Relay Network Nafise Sadeghi Rouhollah Aghajani Estudios Ambientales Cognitive relay cognitive radio outage probability signal to noise ratio Cognitive relay network is a method for optimizing frequency spectrum utilization . What’s important in these networks is to transmit data such that none of primary and secondary users cause destructive interference to other users. Although primary interference affect cognitive network performance, but is neglected in former researches. In this paper, we show cognitive network performance by calculating outage probability. We consider both primary and secondary interference links. Finally, our study is corroborated by representative numerical example. Simulation results demonstrate that increasing interference threshold increase outage probability and increasing data transmit rate cause outage probability increase. 2015 artículo científico 0100-8307 https://www.redalyc.org/articulo.oa?id=467547683028 en http://www.redalyc.org/revista.oa?id=4675 Ciência e Natura application/pdf Universidade Federal de Santa Maria Ciência e Natura (Brasil) Num.6-2 Vol.37 |
