This article investigates how the performance of the primary user is affected by the presence of a spectrum-sharing cognitive user. The performance under both cooperative and non-cooperative cognitive schemes is considered. Primary user's transmission rate, average channel capacity, and average bit error rate are considered as the performance measures. Moreover, the performance is compared with that of a wireless user in a Rayleigh channel, and the gain in performance is found. In addition, a process on how the primary user can accommodate a cognitive user without sacrificing its own performance is explained. Results of this work indicate that the primary user experiences a very close performance in both non-cooperative cognitive and Rayleigh environments. However, the primary user enjoys a pronounced better performance in the cooperative cognitive mode.
