ABSTRACT:
A method for scanning at least a channel of a received signal includes scanning a plurality of frequency bands in sequence and analyzing each frequency band to determine if the frequency band holds the received signal. If it does, the method includes detecting a frequency response of the received signal and detecting a channel characteristic of a channel according to the frequency response of the received signal. The received signal corresponds to the channel.
