ABSTRACT

A comprehensive review on the performance analysis of cognitive radio network that potentially persists iterative rapid channel fluctuation amidst multipath fading environment has been scrutinized. In particular, we have profoundly attempted to peruse the simulation of cognitive radio networks over a sum-of-sinusoids method based Nakagami-m fading channel that allegedly characterizes its impact on the attained throughput. The fading channel is configured using improved Jakes’ model. The simulation results evidently evince that with different values of Nakagami fading parameter (m), the throughput of the cognitive user varies divergently with increase in the number of channels and signal-to-noise ratio (SNR) at cognitive user receiver for interweave and underlay spectrum access techniques respectively. The curves obtained are corroborated using Monte Carlo simulation.
