Effect of Primary Network on Performance of Spectrum Sharing System over Nakagami-m Fading Channel
Author(s): Fahim Khan, Taimour Khan and Muhammad Fahad
Cognitive radio is an emerging radio technology that can improve the efficiency of the radio spectrum utilization. Cognitive radio senses the vacant space in the radio spectrum by changing its operating parameters and uses the vacant spectrum in an opportunistic way and immediately vacates the spectrum bands once the primary user (PU) is detected. The cognitive radio efficiently uses radio spectrum by operating in both licensed and unlicensed bands and avoids the interference with the licensed or unlicensed users. The PU holds the license for a particular band and has the priority to use the channel. The secondary user (SU) can use the vacant bands as long as they do not affect the PU transmission. However, previous research work has ignored the effect of interference from primary netwo... view more»
