Abstract
A method of distinguishing center-frequency-tuned signals from off-tuned signals and noise in a single-channel receiver, comprising: receiving a signal with the single-channel receiver; storing the signal in a memory store; calculating the variance of a time-windowed segment of the signal; storing data representing the variance of the segment in the memory store; calculating the kurtosis of the segment of the signal; storing data representing the kurtosis of the segment in the memory store; comparing the variance data and the kurtosis data to variance and kurtosis thresholds respectively; identifying the segment as center-frequency-tuned if the variance of the segment exceeds the variance threshold and the kurtosis falls below the kurtosis threshold; and identifying the segment as non-center-frequency-tuned if the variance of the segment is less than or equal to the variance threshold and/or the kurtosis is greater than or equal to the kurtosis threshold.
