Abstract
A scan system receives signals within a band from an antenna and divides the band into sub-bands and scans the channels of each sub-band to determine a candidate channel based on the lowest figure of merit (FOM) and includes an on-channel selection block responsive to a received digital signal and operative to select only the on-channel frequencies and to substantially disregard the out-of-channel frequencies from the digital signal. The scan system generates a FOM on-channel signal representing a measurement of the signal quality of the on-channel signal and includes an out-of-channel selection block responsive to the digital signal and operative to select only the out-of-channel frequencies and to substantially disregard the on-channel frequencies from the digital signal and operative to generate a FOM out-of-channel signal representing a measurement of the signal quality of the out-of-channel signal.
