Performance of Eigenvalue-Based Signal Detectors with Known and Unknown Noise Level
Performance of Eigenvalue-Based Signal Detectors with Known and Unknown Noise Level
In this paper we consider signal detection in cognitive radio networks, under a non-parametric, multi-sensor detection scenario, and compare the cases of known and unknown noise level. The analysis is focused on two eigenvalue-based methods, namely Roy's largest root test, which requires knowledge of the noise variance, and the generalized …
