Wireless communication terminal able to change channel and changing method of channel thereof

The present invention relates to a wireless communication terminal, a channel and a channel change method changeable. The wireless communication terminal includes a second at least a portion of the broadband communication frequency bands to form a plurality of channels is divided into a plurality of sub-frequency bands, and receives a radio communication signal via at least one of a plurality of channels, the wireless communication signal the change of the channel to receive is available. As a result, the optimized channel condition can be high quality of communications between the sending terminal and the receiving terminal, and it is possible to prevent a signal interference between each of the receiving terminals connected to the mutually different transmission terminal. In addition, the channel change process quickly and efficiently, it is possible to reduce the power consumed during transmission and reception of the chaotic carrier. Wireless communication, the chaos signal, a broadband, channel, power level, band
