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.

Abstract: A communication apparatus is provided. The communication apparatus includes an RF module for receiving an RF signal, and a down converter, coupled to the RF module, for down converting the RF signal in response to a channel select signal to generate a converted signal. The channel select signal controls the down converter to sweep a plurality of scan trains during a scan frame, and each of the scan trains comprises a plurality of channels, wherein a total channel number of the plurality of scan trains is N, where 32≦N≦78. The communication apparatus also includes a detector, coupled to the down converter, for determining whether the RF signal comprises an ID packet according to the converted signal corresponding to the channels of the plurality of scan trains.

Abstract: A wireless communications includes a first wireless communications and a second wireless communications. The first wireless communications module transmits or receives a first wireless signal in a first frequency band selected from a first frequency range. The second wireless communications module transmits or receives a second wireless signal in a second frequency band selected from a second frequency range, and adjusts a transmission power of the second wireless signal in response to that a frequency offset between the first frequency band and the second frequency band falls within a predetermined range. The first wireless communications module is further configured to determine an in-band range in the overlapping part of the first and second frequency ranges, and a transmission power of the second wireless signal is adjusted in response to a frequency offset between the first frequency band and the second frequency band.
