Cooperative spectrum sensing under unreliable reporting channels

  • Amanda de PaulaEmail author

This article analyzes a cooperative spectrum sensing scheme using a distributed approach with a fusion center considering an unreliable reporting channel. The spectrum sensing is applied to a cognitive radio system, where each cognitive radio sends its decision to a fusion center through a reporting channel, in which an n-out-of-K rule is applied. We compare the performance of the decision rules, analyzing the impact of the errors introduced by the reporting channel, considering the Bayes risk criterion.
