Abstract
According to one embodiment, a wireless communication device includes a receiver, a physical layer processor, a MAC layer controller, and a channel setting unit. The receiver receives wireless signals received by using a plurality of communication channels as a baseband signal. The physical layer processor processes a physical layer of the baseband signal. The MAC layer controller recognizes a first frequency band used by a first communication channel, and determines whether a second frequency band is adjacent to the first frequency band or not. The channel setting unit supplies the first frequency band to the receiver, and controls the physical layer processor depending on information as to whether the first frequency band is adjacent to the second frequency band or not.
Claims20
A wireless communication device comprising:
- a receiver which receives wireless signals by using a plurality of communication channels as a baseband signal;
- a physical layer processor which processes a physical layer of the baseband signal received by the receiver;
- a MAC layer controller which recognizes a first frequency band used by a first communication channel in the communication channels, based on the baseband signal supplied from the physical layer processor, and determines whether a second frequency band used by a second communication channel different from the first communication channel in the communication channels is adjacent to the first frequency band or not;
- and
- a channel setting unit which supplies the first frequency band supplied from the MAC layer controller and used by the first communication channel to the receiver, and controls the physical layer processor depending on information as to whether the first frequency band supplied from the MAC layer controller is adjacent to the second frequency band or not.
A wireless communication method comprising:
- receiving a wireless signal using a plurality of communication channels and down-converting the wireless signal to a baseband signal;
- processing a physical layer in the baseband signal;
- based on the processed baseband signal, recognizing a first frequency band used by a first communication channel, and determining whether a second frequency band used by a second communication channel different from the first communication channel in the communication channels is adjacent to the first frequency band;
- and
- according to information as to whether the first frequency band is adjacent to the second frequency band or not, executing a predetermined process on the baseband signal so as to prevent the baseband signal received from being influenced by an interference signal.
