A method of determining whether a television, TV, band channel is available for use by a TV band device , comprising: tuning to the TV band channel ; down-converting a radio frequency signal received on the TV band channel to yield a down-converted signal ; performing a predetermined number of Fast Fourier Transforms, FFTs, on the down-converted signal and accumulating an energy of respective bins associated with the respective FFTs ; selecting a predetermined number of FFT bins centered at a mandated location of an Advanced Television Systems Committee, ATSC, pilot in the TV Band channel ; and analyzing the selected FFT bins to determine if an energy spike is present in any one of the selected FFT bins , wherein If an energy spike is not present in any one of the selected FFT bins, declaring that the TV Band channel available for use by the TV Band device; else further down-converting the radio frequency signal to a baseband signal and analyzing the baseband signal in the time domain to determine if the baseband signal contains a DTV field-sync or a DTV segment-sync; else correlating the baseband signal with a pre determined wave known to be broadcast by wireless microphone sites and defined at baseband by the following modulating sequence {b} = {+M, -M, +M, -M, +M, -M, +M...}, and if there is a good level of correlation, declaring the TV Band channel is used by a wireless microphone; else declaring the TV Band channel available for use by the TV Band device. tuning to the TV band channel ; down-converting a radio frequency signal received on the TV band channel to yield a down-converted signal ; performing a predetermined number of Fast Fourier Transforms, FFTs, on the down-converted signal and accumulating an energy of respective bins associated with the respective FFTs ; selecting a predetermined number of FFT bins centered at a mandated location of an Advanced Television Systems Committee, ATSC, pilot in the TV Band channel ; and analyzing the selected FFT bins to determine if an energy spike is present in any one of the selected FFT bins , wherein If an energy spike is not present in any one of the selected FFT bins, declaring that the TV Band channel available for use by the TV Band device; else further down-converting the radio frequency signal to a baseband signal and analyzing the baseband signal in the time domain to determine if the baseband signal contains a DTV field-sync or a DTV segment-sync; else correlating the baseband signal with a pre determined wave known to be broadcast by wireless microphone sites and defined at baseband by the following modulating sequence {b} = {+M, -M, +M, -M, +M, -M, +M...}, and if there is a good level of correlation, declaring the TV Band channel is used by a wireless microphone; else declaring the TV Band channel available for use by the TV Band device. further down-converting the radio frequency signal to a baseband signal and analyzing the baseband signal in the time domain to determine if the baseband signal contains a DTV field-sync or a DTV segment-sync; else correlating the baseband signal with a pre determined wave known to be broadcast by wireless microphone sites and defined at baseband by the following modulating sequence {b} = {+M, -M, +M, -M, +M, -M, +M...}, and if there is a good level of correlation, declaring the TV Band channel is used by a wireless microphone; else declaring the TV Band channel available for use by the TV Band device. <EOS>
