A common technique for cognitive radio wideband spectrum sensing is energy/power detection of primary users (PU) in frequency domain. Specifically, power spectrum estimation methods are combined with power detection statistics to test the PU presence. However, when detecting in a particular band of interest these techniques suffer from energy leakage and adjacent channel interference. In this paper,...
In this paper, a model is presented for the low-frequency noise in four-gate FETs (G4-FETs). It combines volume and surface noise sources. The generation recombination noise in the volume of the device originates from fluctuations of trapped charge in the depletion regions. We propose a model for calculating this noise component by evaluating the fluctuation in the cross section of the transistor...
