Abstract

A method for ultra wideband (UWB) wireless communication using channel information. The method comprises the steps of extracting a first channel information including information to generate UWB signals by demodulating received UWB signals and performing channel decoding, generating UWB signals by performing channel coding and modulation according to the first channel information, and transferring the generated UWB signals.
