Constant false alarm rate (CFAR) detection based estimators with applications to sparse wireless channels [PDF]

open access: yes, 2006
We provide Constant False Alarm Rate (CFAR) based thresholding methods for training based channel impulse response (CIR) estimation algorithms for communication systems which utilize a periodically transmitted training sequence within a continuous stream of information symbols. After obtaining the CIR estimation by using known methods in the literature,

Statistical Properties of Energy Detection for Spectrum Sensing by Using Estimated Noise Variance

open access: yesJournal of Sensor and Actuator Networks, 2019
In energy detection for cognitive radio spectrum sensing, the noise variance is usually assumed given, by which a threshold is set to guarantee a desired constant false alarm rate (CFAR) or a constant detection rate (CDR).

CFAR Strategy Formulation and Evaluation Based on Fox’s H-function in Positive Alpha-Stable Sea Clutter

open access: yesRemote Sensing, 2020
The problem of target detection in impulsive non-Gaussian sea clutter has attracted a lot of attention in recent years. The positive alpha-stable (PαS) distribution has been validated as a suitable model for the impulsive non-Gaussian sea clutter.
