Abstract:
This paper focus on the problem of spectrum sensing based on multiple receive antennas. In this context, we propose a novel kurtosis based Combined Second Order Moments (CSOM) as a decision metric allowing to enhance the decision accuracy for both very low SNR environment and an uncertainty on the noise level estimation. Besides, a novel kurtosis based Square-Law Combining (SLC) test metric is proposed. Comparing the proposed approaches to the former sensing techniques shows its better performance in terms of Receiver Operating Characteristics (ROC) and robustness to the noise level estimation errors for the disadvantage of an acceptable complexity loss. Furthermore, the proposed approaches does not necessitate a priori knowledge about the primary signal.
