Multiantenna spectrum sensing for improper signals over frequency selective channels

Abstract

We consider multiple antenna spectrun sensing for improper complex primary user (PU) signals. Past work on this problem is limited to PU Gaussian signals over flat fading channels. We allow non-Gaussian signals over frequency-selective channels. A binary hypothesis testing approach is formulated and a generalized likelihood ratio test (GLRT) is derived using the power spectral density estimator of an augmented sequence. An analytical solution for calculating the test threshold is provided. The results are illustrated via simulations.
