Abstract
A sub-banded ultra-wideband (SB-UWB) system may combine aspects of an orthogonal frequency division multiplexing (OFDM) modulation scheme with aspects of an ultra-wideband system. In one embodiment, the system may use orthogonal waveforms to form an ultra-wideband wireless communications system. In another embodiment, an FFT based implementation of the system may be used to generate and detect an SB-UWB waveform.
