In this paper, the performance of a
secondary user (SU) in an underlay cognitive radio (CR) network over a
generalized-gamma (GG) fading channel in terms of three performance metrics,
namely, outage probability, ergodic capacity, and bit error rate (BER), is
investigated. According to the underlay approach, the transmit power of the SU
should be limited to avoid interference to primary users (PUs). The performance
metrics of the SU in the underlay CR network are theoretically derived and also
obtained with Monte Carlo simulations for a GG fading channel with different fading
parameters. To demonstrate the effect of limited power on the performance
metrics, three different maximum transmit power levels (Pmax), namely, 10, 20,
and 30 dB, are used. The simulation results lead to three conclusions: First,
when high values are chosen for the fading parameters (α, c), the fading
channel gets less distorted and the performance metrics improve. The second
conclusion is that the BER performance gets better as the limited power
increases. The final conclusion is that the BER performance of SUs improves as
the interference power that PUs can tolerate increases.
