Abstract
In this letter, we obtain a generalized expression for the optimal number of cognitive users (CUs), M, for the K-out-of-M rule that minimizes the Bayes risk at the fusion center (FC) over noisy control channels. We show that many existing and new results for optimal M are special cases of the proposed solution. Numerical results are presented using energy detector. However, the expressions for optimal M obtained in this letter are applicable to any detector used in cooperative spectrum sensing.
