Abstract:
A method and system for determining whether a given electromagnetic frequency is in use. An incoming signal is sampled and a test statistic is calculated based on the magnitude of the received samples and a predetermined constant. A determination is then made regarding whether the frequency is in use, based on whether the test statistic has exceeded a threshold.
