Abstract: A communication apparatus is provided. An RF module receives an RF signal. An analog down converter down converts the RF signal in response to a band select signal to generate a first converted signal in a specific frequency band. An analog-to-digital converter converts the first converted signal into a digital signal. A digital down converter down converts the digital signal in response to a channel select signal to generate a second converted signal. The channel select signal controls the digital down converter to sweep a plurality of scan trains during a scan frame. Each of the scan trains includes a plurality of channels. The total channel number of the plurality of scan trains is N. A detector determines whether the RF signal includes an ID packet according to the second converted signal corresponding to the channels of the plurality of scan trains.
