Spectrum sensing in cognitive radio (CR) is a basic requirement to protect the primary user (PU) from bad interference. However, sensing has two main challenges. Firstly, the CR is required to sense the presence of the PU under very low signal-to-noise ratio (SNR) that prolongs the sensing time. Secondly, some CR nodes may suffer from deep fading and shadowing effects, which may produce false sens...
