Spectrum sensing based on fractional lower order moments for cognitive radios in α-stable distributed noise
The traditional spectrum sensing methods based on second order statistics are in general not applicable to detecting a primary user with unknown parameters in non-Gaussian noises. This paper presents a novel spectrum sensing scheme based on fractional lower order moment (FLOM) for the detection of a primary user in non-Gaussian noise that are modeled by the α-stable distribution. The new detect...

متن کاملHigher-Order Cyclostationarity Detection for Spectrum Sensing
Recent years have shown a growing interest in the concept of Cognitive Radios (CRs), able to access portions of the electromagnetic spectrum in an opportunistic operating way. Such systems require efficient detectors able to work in low Signal-to-Noise Ratio (SNR) environments, with little or no information about the signals they are trying to detect. Energy detectors are widely used to perform...
متن کاملExploiting Polarization for Spectrum Awareness in Cognitive Satellite Communications
The continuously increasing demand of spectrum and current static spectrum allocation policies are rendering the available radio spectrum scarce. To address the problem of spectrum scarcity in the satellite paradigm, cognitive satellite communications has been considered as a promising technique. In addition to the existing spectrum sharing dimensions such as frequency, time, and space, polariz...
