Abstract
Wireless communication systems primarily depend on the availability of bandwidth. Cognitive radio has been realized as an effective means to maximize the bandwidth for internet and other communication applications. Multiple cognitive radios perform spectrum sensing in cooperation to mitigate the effects of fading. A specific number of cooperating cognitive radio users are responsible to form the decision at the fusion center for spectrum occupancy and is called the global decision threshold. In this letter, we find the global threshold which maximizes the throughput of the cognitive radio users while keeping a constraint on the interference to the licensed primary user. It is observed that for every interference value below the constraint, the throughput of the cognitive radio users maximizes at a particular value of the global decision threshold.
