<p>Methods, systems, and media for detecting usage of a radio channel are provided. In some embodiments, methods for detecting usage of a radio channel are provided, the methods comprising: collecting noise samples on the radio channel from a radio receiver; determining a noise empirical cumulative distribution function using a hardware processor; collecting signal samples on the radio channel from the radio receiver; determining a signal empirical cumulative distribution function using a hardware processor; calculating a largest absolute difference between the noise empirical cumulative distribution function and the signal empirical cumulative distribution function using a hardware processor; and determining that the radio channel is being used when the largest absolute difference is greater than a threshold using a hardware processor.</p> |
