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.
