Primary System Detection for Cognitive Radio: Does Small-Scale Fading Help?
2007 (English)In: IEEE Communications Letters, ISSN 1089-7798, Vol. 11, no 10, 799-801 p.Article in journal (Refereed) Published
We consider the effect of small-scale fading on thedetection of weak signals in cognitive radio systems.We formulatea model for the detection problem taking fading into account,and give the associated likelihood ratio tests. Additionally we givean expression for the asymptotic detection performance and usethis to consider the tradeoff between the detection performanceand the coherence time and bandwidth of the channel.
