On the Higher Order Statistics of the Channel Capacity in Dispersed Spectrum Cognitive Radio Systems Over Generalized Fading Channels
Tsiftsis, Theodoros A.; Foukalas, Fotis; Karagiannidis, George K.; Khattab, Tamer ( Institute of Electrical and Electronics Engineers Inc. , 2016 , Article)This work is devoted to the study of dispersed spectrum cognitive radio (CR) systems over independent and nonidentically distributed (i.n.i.d.) generalized fading channels. More specifically, this is performed in terms of ... -
Underlay cognitive radio : What is the impact of carrier aggregation and relaying on throughput ?
Diamantoulakis, Panagiotis D.; Pappi, Koralia N.; Muhaidat, Sami; Karagiannidis, George K.; Khattab, Tamer ( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)In this paper, we investigate joint relay selection and optimal power allocation, as a means to maximize the achievable rate of an underlay cooperative cognitive radio with carrier aggregation, taking into account the ... -
