Abstract
A wireless communication terminal capable of changing a channel, and a channel changing method of the wireless communication terminal. The wireless communication terminal generates a plurality of channels by dividing at least part of a frequency band for ultra-wideband communications into a plurality of frequency sub-bands, receives a radio signal in at least one of the plurality of the channels, and changes a channel for receiving the radio signal. Accordingly, high quality communications are feasible between the transmitter terminal and the receiver terminal in an optimized channel environment, and signal interference between the receiver terminals connected to different transmitter terminals can be prevented. Additionally, it is possible to carry out the channel change rapidly and efficiently and to reduce the power consumption required to transmit and receive radio signals comprising a chaotic carrier signal.

12. A channel changing method of a wireless communication terminal, comprising:
-
generating a plurality of channels by dividing at least part of a frequency band for ultra-wideband communications to a plurality of frequency sub-bands, and transmitting a first radio signal from a first terminal to a second terminal by selecting one of the channels; determining communication state of the selected channel by detecting energy of a second radio signal transmitted from the second terminal to the first terminal; determining whether to change the selected channel according to the communication state; and transmitting and receiving radio signals in the determined channel. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
