Abstract :
In this paper, coexistence of cellular network with cognitive radio (CR) users or secondary users (SUs) has been studied. More precisely, an analytical frame work for downlink interference modelling in a cognitive radio frequency planned environment has been developed. Outage performance of a PU in a frequency planned cognitive radio network has been investigated. Dynamic spectrum sharing with spectrum underlay approach has been considered. Further, we assume correlation amongst different log normal interferers from several co-channel BSs and cognitive users. A simulation test bed for evaluating outage probability in cognitive radio cellular networks has been developed. Effects of several network and channel parameters are shown on outage probability of a PU.
