摘要：A method for classifying a signal is disclosed. The method can be used by a
station or stations within a network to classify the signal as non-cooperative (NC) or atarget signal. The method performs classification over channels within a frequencyspectrum. The percentage of power above a first threshold is computed for a channel.Based on the percentage, a signal is classified as a narrowband signal. If the percentageindicates the absence of a narrowband signal, then a lower second threshold is applied toconfirm the absence according to the percentage of power above the second threshold.The signal is classified as a narrowband signal or pre-classified as a wideband signal basedon the percentage. Pre-classified wideband signals are classified as a wideband NC signalor target signal using spectrum masks.
