Abstract
Cooperative spectrum sensing (CSS) is an efficient method, which is used to detect the presence/absence of primary user (PU) signal in the received spectrum at the secondary user (SU). Clustering is a vector quantization technique that classifies the observed signal into some fixed number of clusters depending upon the nearest mean. In this work, the K-mean clustering algorithm is used to classify the SUs received signal into the signal available class or signal unavailable class. The channel between the PU and SUs is assumed to be generalized (α–η–μ and α–κ–μ) fading channels. The performance of the proposed algorithm is compared with the conventional method of CSS with energy feature vector and found to be superior to that.
