Abstract
The present invention provide a method and system of dynamically estimating a coefficient of variation of the fluctuation of a waveform and an optimal binary detection threshold using the estimated coefficient of variation. The system discriminates between noise signals and signal-plus-noise signals of a digitized signal by comparison with a threshold. The noise and signal-plus-noise signals are further used to determine a mean noise floor level and a standard deviation, respectively. Subsequently, the system determines the coefficient of variation based on the ratio of standard deviation to mean. The optimal binary detection threshold is calculated using the coefficient of variation, presets for cumulative probability of false alarm and collection time.
