Abstract: The UWB(ultra wide band) technology is a new technology with revolutionary significance in the short-range wireless communication field. In this paper, the design theory and structure of the UWB wireless communication system based on widely applied OFDM(orthogonal frequency-division multiplexing) are analyzed, the method of producing MB-OFDM-UWB signal is expounded systematically, and the signal is simulated. The analyses lay a foundation for the application of OFDM-UWB signal in the actual communication system.
Key words: UWB(ultra wide band); multi-band; OFDM(orthogonal frequency-division multiplexing) signal
