Recently, a new approach for designing detectors for cooperative spectrum sensing has been coined. It applies an incoming inequality index, which is normally used in economic and social sciences, to build a test statistic that operates on the entries of the received signal sample covariance matrix. The first detector designed using this approach was the Gini index detector (GID). This letter devises the Atkinson index detector (AID), which is shown to outperform the GID in many situations, with the special attribute of attaining a time complexity that grows linearly with the number of secondary users.
