Subtitle Signal Classification in Fading Channels Using Cyclic Spectral Analysis
Cognitive Radio (CR), a hierarchical Dynamic Spectrum Access (DSA) model, has been considered as a strong candidate for future communication systems improving spectrum efficiency utilizing unused spectrum of opportunity. However, to ensure the effectiveness of dynamic spectrum access, accurate signal classification in fading channels at low signal to noise ratio is essential. In this paper, a h...

متن کاملModulation Classification Using Spectral Features on Fading Channels
Modulation classification plays a key role in demodulation of the received signal for extracting the required information. Modulation classification is a difficult task when there is no information about the received signal (Blind Classification) and especially in presence of multipath fading and white guassian noise. Emerging applications of automatic modulation classification (AMC) in militar...
متن کاملMulti-User Signal Classification via Cyclic Spectral Analysis
Guenther, Brent. M.S.EGR., Department of Electrical Engineering, Wright State University, 2010. Multi-User Signal Classification Via Cyclic Spectral Analysis. This research develops and evaluates several different methods for multi-user signal classification via cyclic spectral analysis. The first method uses the spectral correlation function (SCF) through temporal smoothing with the use of hig...
متن کاملSignal modelling in wireless fading channels using spherically invariant processes
In this paper we propose the application of spherically invariant random processes for joint modeling of the fluctuations of the signal envelope and phase in narrowband wireless fading channels. In this model, phase has uniform distribution (which is very common in fading channels), while the envelope can be distributed according to an arbitrary distribution law (which includes Rayleigh as a sp...
